I see this thing occasionally when reading news in group. I cant reproduce it at will.

This screen shot is from article buffer, you can see the first line starts with "I tend to ... " is displayed twice in the screen (bottom also same line). In fact this messages was long, the line "I tend to ..." displayed at the bottom at the beginning. then I needed to hit SPC to read remaining part of the message. So the last line stays there I hope my description is clear. -- YYR

So the last line stays there Eli, if you look at the image included in this bug report, this looks like the same display bug that I've seen a few times. It's as if Emacs isn't clearing some parts of the screen when scrolling. (Sometimes.) I still haven't been able to make a test case for this.

Probably some redisplay optimization that doesn't exactly DTRT.
When this happens, does it help to type "M-x redraw-display RET"? If
it does, then, in the absence of a reproducible test case, all I can
suggest is gather more info to narrow the range of possible
offenders. Start by rebuilding Emacs with -DGLYPH_DEBUG=1, then start
Emacs with stderr redirected to a file, toggle redisplay tracing with
"M-x trace-redisplay RET", and wait till the problem happens. When it
does, make the window with incorrect display the currently selected
window, and type "M-x dump-glyph-matrix RET". Finally, send the
contents of the redirected stderr here.
There are also several variables that inhibit certain redisplay
optimizations. They are defined in xdisp.c and are available only
when Emacs is compiled with -DGLYPH_DEBUG=1:
#if GLYPH_DEBUG
DEFVAR_BOOL ("inhibit-try-window-id", inhibit_try_window_id,
doc: /* Inhibit try_window_id display optimization. */);
inhibit_try_window_id = 0;
DEFVAR_BOOL ("inhibit-try-window-reusing", inhibit_try_window_reusing,
doc: /* Inhibit try_window_reusing display optimization. */);
inhibit_try_window_reusing = 0;
DEFVAR_BOOL ("inhibit-try-cursor-movement", inhibit_try_cursor_movement,
doc: /* Inhibit try_cursor_movement display optimization. */);
inhibit_try_cursor_movement = 0;
#endif /* GLYPH_DEBUG */
By selectively turning off each of these optimizations, we could zero
in on the optimization that causes this bug. However, using these
variables effectively needs some initial ideas about the possible
causes, so I think gathering the info as suggested above is best as
the first step.

Unfortunately, I hadn't compiled Emac with -DGLYPH_DEBUG=1 (but am going to do it now), but at least I managed to take some screen shots now, which may give somebody an idea about what the problem is, perhaps. (Sorry for the big email.) The first image is me reading a blog post normally. The second is me typing `C-h f redisplay'. Only the top half of the display is actually refreshed, leaving the image apparently being displayed in the help buffer. And the last image is me lowering and raising the window, forcing a redisplay, which makes Emacs look like it should again.

Is this reproducible, e.g., with that blog post? I've seen in the past redisplay problem with images, but they would disappear in a fresh session of Emacs, even if I made exactly the same gestures as the ones which reproduce the problem in a long-running session. Do you have the same experience? When you do have Emacs built with -DGLYPH_DEBUG=1, and this happens, invoke "M-x trace-redisplay RET", and tell what it prints to stderr when you do whatever is needed to reproduce the problem.

I'd say that it happens about, er, once a thousand times that Emacs displays a message, and it's totally unreproducible. I *think* what happens is always that this only happens when I scroll the buffer down and it reaches the end. After the end of the buffer, the bottom of the window should be totally blanked out, but sometimes (if there's an image in the part that should have been blanked out after scrolling), it doesn't happen. So my feeling is that there may perhaps be an optimisation relating to clearing the window after end-of-buffer. But that may be totally wrong, of course. :-) > I've seen in the past redisplay problem with images, but they would > disappear in a fresh session of Emacs, even if I made exactly the same > gestures as the ones which reproduce the problem in a long-running > session.

I'm now running with GLYPH_DEBUG and STDERR to a file, so I should be able to get a trace the next time... -- (domestic pets only, the antidote for overdose, milk.) bloggy blog http://lars.ingebrigtsen.no/

Ok, I got a display bug, and it was of the same time as before: After scrolling, area after the end of the buffer wasn't cleared, leaving the image. I switched on trace-redisplay, paged back and forth, which was still buggy, and then did a matrix dump. Then the window fixed itself suddenly without me doing anything. Here's the output from the log file. redisplay_internal 0 0x372ff70 (*Summary nntp+news.gmane.org:gwene.org.jwz.blog*): same window start 0x372ff70 (*Summary nntp+news.gmane.org:gwene.org.jwz.blog*): 1 0x5343aa8 (*Article nntp+news.gmane.org:gwene.org.jwz.blog*): same window start 0x5343aa8 (*Article nntp+news.gmane.org:gwene.org.jwz.blog*): 1 0x5168d70 (sendmail.el): same window start 0x5168d70 (sendmail.el): 1 0x4bc23a0 (smtpmail.el): same window start 0x4bc23a0 (smtpmail.el): 1 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_internal 0 0x5343aa8 (*Article nntp+news.gmane.org:gwene.org.jwz.blog*): forced window start redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_internal 0 0x5343aa8 (*Article nntp+news.gmane.org:gwene.org.jwz.blog*): forced window start redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_preserve_echo_area (8) redisplay_internal 0 redisplay_internal 0 0x372ff70 (*Summary nntp+news.gmane.org:gwene.org.jwz.blog*): same window start 0x372ff70 (*Summary nntp+news.gmane.org:gwene.org.jwz.blog*): 1 0x5343aa8 (*Article nntp+news.gmane.org:gwene.org.jwz.blog*): same window start 0x5343aa8 (*Article nntp+news.gmane.org:gwene.org.jwz.blog*): 1 0x35c3880 ( *Minibuf-1*): same window start 0x35c3880 ( *Minibuf-1*): 1 0x5168d70 (sendmail.el): same window start 0x5168d70 (sendmail.el): 1 0x4bc23a0 (smtpmail.el): same window start 0x4bc23a0 (smtpmail.el): 1 redisplay_internal 0 0x35c3880 ( *Minibuf-1*): same window start 0x35c3880 ( *Minibuf-1*): 1 redisplay_preserve_echo_area (8) redisplay_internal 0 trying display optimization 1 0x35c3880 ( *Minibuf-1*): optimization 1 redisplay_internal 0 0x35c3880 ( *Minibuf-1*): same window start 0x35c3880 ( *Minibuf-1*): 1 redisplay_preserve_echo_area (8) redisplay_internal 0 trying display optimization 1 0x35c3880 ( *Minibuf-1*): optimization 1 PT = 171, BEGV = 1.

And then suddenly the Emacs frame updated itself and everything was OK. So I'm not sure how that relates to the blog, but it was after the glyph dump, at least. >> Here's the output from the log file. > > I will study it, but it is important for me to understand how this log > is related to whatever you did in Emacs. Does this reflect only the > "page back and forth, and the matrix dump", or does it include more > stuff? What I did was read the message (from the *Summary* buffer), hit SPC, and the *Article* buffer scrolled forwards and had the wrong display. Then I jumped to and xterm to read the instructions I had saved in a file there. Then I think I went back to the Emacs frame, typed `M-x trace-redisplay', scrolled back and forth (with the bug still displaying), then did a dump-glyph-matrix, then went back to the xterm, and then Emacs spontaneously fixed itself, and then I went back to the Emacs frame and switched the trace off. I think. :-) -- (domestic pets only, the antidote for overdose, milk.) bloggy blog http://lars.ingebrigtsen.no/

Yes, the only text in the buffer was the Link thing, and that was probably on the second line. However, the window was (let's see) 43 lines tall. The image was (faultily) displayed right below the Link. > Btw, next time please use (dump-glyph-matrix 2), to get more > information about the glyphs on display.

OK, that's my misreading of the dump: the "(0)" part means the line is disabled in the glyph matrix, i.e. not displayed. > The image was (faultily) displayed right below the Link. So the bug seems to be that we don't clear those empty lines which occupied the screen estate of the image.

Also, I just installed a few changes on the emacs-24 branch that make the matrix dump better, please resync if you can.

Could you describe in more detail what happened to cause the text at the end of the buffer be displayed instead of the image? Is it that the buffer included an image and also some text, and that buffer was scrolled such that the image went out of view and the text came into view? Or was it some other scenario, like maybe switching buffers in the window? Andreas, perhaps you also could give such details about your case? I think I see the code that could be the culprit, but I need to understand better how the new display replaced the old one, to dig deeper. TIA

I had a beautiful example of the bug last night, but I fumbled and make
the window go away before I could get a screen shot.
And the redisplay log was truncated because I had started two Emacsen
pointing to the same file. *sigh*
Anyway, here's the bits I could salvage from the log, and a glyph dump.
To explain what happens is that I have a window that has an image in
it. When I then scroll the buffer forwards, so that the window displays
the end-of-buffer, and the image occupied (visually) part of the window
after the end-of-buffer, then the rest of the window isn't blanked.
Ok, that explanation didn't make much sense.
I'll try to draw.
Here's what the window looks like first, when everything is OK:
-----------------------------
| bla bla bla |
| bla bla bla |
| |
| -------- |
| |** ***| |
| |*image| |
| |** ***| |
| |** ***| |
| -------- |
| |
| bla bla |
| bla bla |
-----------------------------
Then I scroll.
-----------------------------
| foo |
| zot |
| more foo |
| this is the end of the |
| buffer |
| |
| |** ***| |
| |** ***| |
| -------- |
| |
| bla bla |
| bla bla |
-----------------------------
And the buffer ends where it says. :-)
So I get the bottom half of the image, and then whatever was after the
image.
So it's like it decides that it doesn't have to blank the window after
end-of-buffer if end-of-buffer happens in the middle of the image that
was displayed there. If you understand what I mean. :-)

If you understand what I mean. :-) I think I do understand. My suspicion is that we somehow fail to realize that the screen estate formerly occupied by the image, and everything that follows it, needs to be cleared in its entirety. On the display engine level, the image takes just one "line" (called "glyph row"), and perhaps we somehow don't realize that the height of that "line" is large, and all of that needs to be cleared, not just the number of text lines of "normal" height that will replace the image on display. Thanks for the details, they confirm my suspicions. I now need to find whodunit in the code...

I'm in the bad situation, that one of my laptops (at work) produces the display bug permanently. Often, just scrolling or page up/down is sufficient. That Emacs stanza is almost useless for me, but there's no recipe for reproducing outside that machine. Maybe we could arrange that I take it home, and provide you access. Over night, or over weekend. Let me know. Best regards, Michael.

Please apply the patch below and run with it for a while. It makes
the output of trace-redisplay more voluminous, but I don't see how
else we could catch the problem. When the problem happens again,
please post the results.
Here's my analysis of what is involved; perhaps it will help you read
the output and make some changes on the spot, if needed.
The clearing of portions of display that no longer display anything is
done as part of dispnew.c:update_window. It does that as part of the
call to update_window_line, when the latter is passed a screen line
(a.k.a. "row") that should be empty on display. Such empty lines have
a single glyph (an "invented" blank character with charpos equal to
point-max), whose sole purpose is to facilitate clearing of empty
lines. These empty lines have the enabled_p flag set, which means
they should be displayed. (update_window ignores lines whose
enabled_p flag is reset, because these do not correspond to any part
of the displayed text.)
So, for us to fail to clear these empty lines, I see several possible
reasons:
. the logic in update_window somehow skips the loop that starts at
line 3495 and which displays the empty lines past the end of the
buffer; or
. some redisplay optimization in xdisp.c decides that those parts of
display do not need to be updated, and thus excludes them from the
glyph matrix it constructs in w->desired_matrix, so that those
lines are not updated by update_window; or
. the function x_clear_end_of_line, which is called by
update_window_line, or its terminal-specific back-end (e.g.,
xterm.c:x_clear_frame_area), which implements the meat of that
function, somehow fail to clear the correct portion of the display.
The patches below are designed to report enough info for us to be able
to tell which of the above hypotheses, if any, is true.
Btw, any idea when these problems started happening? Is it an old
problem, or did it start to appear only recently?
Thanks.

Maybe. The machine runs "Tubuntu 12.04", which is an Ubuntu bundle from my employer. But I haven't seen other anomalies on that machine, and most of the packages are native Ubuntu ones. The differences are mainly user policy and alike. I'll see whether I could find another Tubuntu machine, and cross-check whether it is a hardware problem. The problem is that Tubuntu is not widespread (managers are focussed on MS Windows, and they rule); I don't know whom to ask here at Berlin. But there is a company-wide Tubuntu mailing list ... >> The better way might be that you give me a special patch producing >> whatever traces could help in analysis. > > I will try to think about it.

Bisecting my ~/.emacs, the following form provokes the display error for me:
(add-to-list 'default-frame-alist
'(font . "-misc-fixed-bold-r-normal-*-15-*-iso8859-1"))
On other machines, there is the same ~/.emacs w/o problems. On the
machine in question, I have two matching fonts:
-misc-fixed-bold-r-normal--15-120-100-100-c-90-iso8859-1
-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso8859-1
Does this tell you anything?

Not really, unfortunately: I know very little about fonts and how Emacs uses them. But if we continue your line of investigation: does removing one of these fonts solve the problem with the original ~/.emacs?

It happens for both fonts. I've tested
(add-to-list 'default-frame-alist
'(font . "-misc-fixed-bold-r-normal--15-120-100-100-c-90-iso8859-1"))
and
(add-to-list 'default-frame-alist
'(font . "-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso8859-1"))
Anyway, here is a recipe for reproduction:
1. C-x C-f "a larger file, with a no space in last line, first col"
2. M->
3. C-p
4. Use mouse wheel to scroll buffer up
It doesn't happen always, but often. Depends on redisplay calls, I
suspect. See enclosures, which show a superfluous "(".

I tried to reproduce this, including installing and using a misc-fixed
font, but couldn't see any such artifacts left after scroll.
Do you see the problem with these fonts on a different system?
Does anyone else see this?

Unfortunately, I cannot match either of your two images with the corresponding dump of the glyph matrix: there are small inconsistencies in both the "OK" and the "not OK" cases. For example, the first image shows "Top L1" in the mode line of the window that displays the article, but the matrix dump says: 68: (1) ' 1:--- . news:g.c.w.arnoldzwicky Austenian humbleb... Top L19 (Article) ' which is line 19. This is a minor discrepancy, but since there are many similar discrepancies, some of which are probably parts of the bug, I feel I have no firm ground from which I can begin studying the data and making hypotheses about what went wrong. Could you please produce 2 sets of screenshot+matrix dump which are coherent with each other? I must be sure that when I see a discrepancy, it is part of the bug, not some artifact that needs to be ignored. Also, I don't understand the second screenshot: which parts of it are correct and which are bogus? The text before the image looks unfinished, but its continuation, starting with screen line 20, which is clearly present in the glyph matrix dump, is not shown. Are you saying that Emacs was supposed to display that continuation, but never did, and instead left the old parts on display? Thanks.

I may have matched up the wrong bits of the log file or something. I've now redone it, but made sure that each log file bit really belongs to the image. > Could you please produce 2 sets of screenshot+matrix dump which are > coherent with each other?

I've produced four screenshots instead, which should make it clearer what it's supposed to look like, and what's the bug. First, I've selected the article, and it's displaying the topmost part of the article, and everything is fine.

Then I've scrolled the article down, and everything is still fine.

Then I've scrolled the article back up again, so we get the same display as in the first image.

And now for the buggy display. I've scrolled the article down again, and we see lots of the remaining image from the pre-scrolled buffer, and text is also missing, if you compare with the second image.

Hopefully I've matched up the right parts here now. And thanks again for looking into this. This type of bug is pretty tedious to chase down. I've shrunken the images somewhat this time, and converted to .jpg, to avoid a very large mail. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no

Thanks, and sorry again for a _really_ long delay. Based on the stuff you collected and the screenshots, it sounds like Emacs doesn't clear and doesn't redraw the parts of the screen which become corrupted, amazing as that sounds. The only difference between the "good" and the "bad" output is that in the latter case, for some reason, Emacs stops clearing and redrawing screen lines below some Y coordinate, and all the stuff which was there before that stays put instead of being replaced by the new stuff. I'd like to prepare an additional patch which will allow you to collect more data that might reveal why Emacs behaves like that. In order to test the patch, is it possible for you to give me instructions for how to display that article, starting from "emacs -Q"? Thanks in advance. I think we are making progress, albeit slowly (my fault, not yours).

I had forgotten about this entry point to Gnus. `eval'-ing this from "emacs -Q" should work: (gnus-fetch-group "nntp+news.gmane.org:gwene.com.wordpress.arnoldzwicky" '(3401)) although you will be queried about the self-signed certificate. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no

Thanks, that was easy enough. Granted, I don't see any redisplay
problems with that article, like you do.
Below please find a new patch to add trace data. This is _instead_ of
the previous patch, not in addition to it, and it's relative to the
current master (I hope the problem is still visible with the current
master).
After applying the patch, please again do whatever is needed to
reproduce the problem, and please tell me which part(s) of the trace
are emitted when the display becomes corrupted.
Before invoking "M-x trace-redisplay", please disable
blink-cursor-mode (as it triggers too many unnecessary redisplay
cycles that muddy the water), and also delete ("C-x 0") the summary
window, so that redisplay has less windows to refresh (which will
again make the signal to noise ratio of the trace better).
Thanks.
