Subject: Window shrinks with each invocation
Date: Fri, 14 Nov 2008 15:25:42 +0100

The Emacs window shrinks with each invocation:
1. Start a KDE 3.5.10 session.
2. Invoke Emacs.
3. Maximize Emacs.
4. Press PrintScrn (starts Ksnapshot).
5. Make sure that "Include window border" is unchecked.
6. Press "New screenshot".
7. Press "Save as...".
8. Create a direcectory.
9. Enter "emacs_window_shrinking_00.png" in the filename line.
10. Save.
11. Close Emacs.
12. Invoke Emacs.
13. Switch Back to Ksnapshot.
14. Press "New screenshot".
15. Press "Save as..." (Ksnapshot will suggest the next filename
automatically by incrementing the number in the previously used filename).
16. If the two previously saved images differ in size, go to step 10.
17. Execute "file *" in the directory that was created in step 8.

After following these steps I get the following output from the file
command in step 17:

It looks like Emacs window height decreases with 40 pixel each
invocation (except the first an last one). This does not happen with any
other program. Emacs is unusual in that it only accepts certain sizes,
while other programs can be resized freely. It probably has something to
do with that.

Which version of Emacs are you using, and which X toolkit?

Could this be Bug#58?

Maybe, I did not find a link to the bug tracker, like for all other
software projects. Emacs only has an e-mail address for bug reports, so
I could not search existing reports first, like I usually do.

Emacs can't be compiled with Qt.  Which X toolkit did you use to compile
Emacs?

Also, could you try with Emacs CVS, and see if the problem still exists?

You can find the report here:

    http://debbugs.gnu.org/cgi/bugreport.cgi?bug=58

Do you see any similarities?

So it seems to be Xaw3d.

Could you try with emacs-23 (it's also available in Gentoo) and see if
the problem is already fixed there?

The bug does not happen with default configure options, nor if I try
with ./configure --with-x-toolkit=athena.


I also tried the Gentoo package app-editors/emacs-cvs. It behaves like
the manual CVS build after I executed "eselect emacs set emacs-23" (as
expected).

So the bug seems to be fixed in CVS. Is there a newer released version
than 22.3 that I could try? Or is there a patch which fixes this bug,
that distributions could apply to the 22.3 package? (Gentoo already
applies some patches to it, so they could fix this as well.)

I am not sure what causes it, sorry.  I don't recall any bug reports
with the symptoms you described.  Probably the only way to find out is
to bisect CVS revisions, and I don't have the time to do this at the
moment.
