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.

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.
