[Message part 1 (text/plain, inline)]

Jan,

Thanks for responding.  I'm sorry that you didn't get much useful
information from my initial report.  Please let me try again, and I
will make an effort to be clearer this time.

First, I'd like to provide you with some system information.


Operating System:

  (1:0)srevilak:~$ cat /etc/SuSE-release 
  openSUSE 11.2 (i586)
  VERSION = 11.2
  (0:0)srevilak:~$ uname -a
  Linux srevilak 2.6.31.5-0.1-desktop #1 SMP PREEMPT 2009-10-26 15:49:03 +0100 i686 i686 i386 GNU/Linux


Window Manager:

  (0:0)srevilak:~$ kde4-config --version
  Qt: 4.5.3
  KDE: 4.3.1 (KDE 4.3.1) "release 6"
  kde4-config: 1.0


Contents of .Xresources (a single line, containing a comment):

  (0:0)srevilak:~$ cat .Xresources
  ! .Xresources


Contents of .emacs (a single line, containing a comment):

  (0:0)srevilak:~$ cat .emacs
  ; .emacs

Finally, to be sure that ~/.Xresources agrees with our current
environment.

  (0:0)srevilak:~$ xrdb .Xresources



First, I will start emacs with the command line

  /usr/local/emacs-23.1.91/bin/emacs --no-init-file --no-site-file -geometry 86x44-0+0 

figure-1.png shows a snapshot of my screen after starting emacs.  As
you can see, emacs occupies most of the vertical space on the screen.

Next, I will quit emacs, then run the following command line

  /usr/local/emacs-23.1.91/bin/emacs --no-init-file --no-site-file -geometry 86x45-0+0

Notice that I have increased the height from 44 to 45, which is just a
little too large to fit on the screen; the rest of the command line is
unchanged.  The result of this appears in figure-2.png.

Observe that figure-1.png and figure-2.png are quite different.


As you noted before, this could be the Window Manager's doing.  For my
third (and final) snapshot, I would like to provide evidence which
suggests that it is not the window manager.

    /usr/bin/emacs --no-init-file --no-site-file -geometry 86x45-0+0

Above, /usr/bin/emacs is emacs 23.1.1, as packaged with OpenSUSE 11.2
(you'll see this from emacs' splash screen).  The result of running
this command appears in figure-3.png.  As you can see, figure-3.png
resembles figure-1.png much more than figure-2.png.


The difference between figure-2.png and figure-3.png is the core of my
issue.  Specifically,

 * When Emacs-23.1.1 is confronted with a geometry that is too large
   for the height of the screen, then emacs-23.1.1 respects the
   geometry as best as it can.  In figure-3.png, we see that
   Emacs-23.1.1 took up as much of the vertical screen space as was
   possible.

 * When Emacs-23.1.91 is confronted with a geometry that is too large
   for the height of the screen, then emacs-23.1.91 does not try to
   respect the geometry as best as it can.  As you can see from
   figure-2.png, emacs-23.1.91 opted for a much smaller height.  (In
   figure-2.png, you can also see a very different appearance in the
   splash screen itself.)

In summary, I believe that the behavior shown in figure-3.png (produced by
emacs-23.1.1) is more correct than the behavior shown in figure-2.png
(produced by emacs-23.1.91).

Please let me know if you'd like me to provide any additional details.

Steve Revilak
