From: David McArthur <david <at> davidmcarthur.com> To: bug-gnu-emacs <at> gnu.org Subject: 23.1; overprinting / cursor misalignment after certain characters Date: Fri, 28 Jan 2011 10:41:31 -0500
Upon typing certain characters in any buffer (including the minibuffer)
the cursor becomes misaligned and text is overprinted. These characters
are: AKkRrTVWwXxYyZ. This problem only occurs when I have my second
monitor enabled.
The cursor is a blinking black box such that when the cursor is on top
of text, the text is printed in inverse (off-white). What happens after
typing one of AKkRrTVWwXxYyZ is that the black box is moved to the next
position, but the character I just typed blinks as though the cursor
were still on top of it. The next letter I type then appears twice:
both in the correct position, and also overprinted on top of the problem
character to the left. Also, the problem character is then re-printed
one position to the left of where I typed it, overprinting on the
character before it. Further typing appears normally, as long as the
characters are not any of AKkRrTVWwXxYyZ.
For example, if I type "text" weird behavior starts after I type the
lowercase "x". What I see before I type the second "t" is "tex" with
the blinking black box to the right of x, but x is also blinking
(alternating black and off-white). After typing the second "t", what I
see is "t#*t" where # is "x" printed on top of "e" and * is "t" printed
on top of "x". If I move the cursor away and type C-l the text is
redrawn correctly, but if I move the cursor back over the problematic
characters, the overprinting reoccurs.
This is on my laptop running Ubuntu Maverick. The problem occurs when I
have my external monitor enabled (regardless of which monitor the emacs
window is on). When the external monitor is disabled, the problem does
not occur.

While this may very well be an Emacs bug, I think there's a chance this
is a bug in your X server (at least, I've seen somewhat similar problems
in the past with a bug in some of the acceleration code in the `nv'
driver).
Can you maybe try to fiddle with your X11 driver, like turning off the
acceleration, and/or switching between EXA, UXA, XAA, and/or whichever
other acceleration framework they came up with?

Hi. Can you try a newer Emacs version? 23.2 has been out a while. If you can try trunk also that would be great (see http://savannah.gnu.org/projects/emacs/). Does the situation fix itself if you do C-l or iconify and restore the Emacs frame? Can you put the cursor on one of the characters and do C-c C-x C-= and mail the results? Thanks, Jan D.

C-c C-x C-= is undefined Am I trying to do xscheme-send-control-x-interrupt?

Okay, I'll try this next.

I don't know anything about X11 drivers, so this may take me a little while to figure out how to do. I'll try it second.
