bug#1346: Window shrinks with each invocation

[Erik]

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.

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.

RE: bug#1346: Window shrinks with each invocation

[Drew Adams]

This message from the bug mailing list makes me think that each bug-list mailing
should include a link at the bottom that takes you directly to the entry for
that message on the bug-list web site.

Users should not need to have memorized the bug web site URL, type it in, and
navigate to the particular bug #. They should be able to just click a link in
the mail to get to the appropriate bug entry and thread.

That is typical behavior for the bug mail communications I'm aware of. It is
typical for web-based applications that notify users by email.

You can see from the last line below that this would also help avoid filing new
bugs for the same problem.

You can find the report here:

Do you see any similarities?

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.

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

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?

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.)
