OpenGL in KDE only on top 420 pixels

Hi all,

I'm currently running KDE 3.5.6 on 6.2-RELEASE, and I've tested OpenGL with
the screen savers from the "OpenGL Screen Sav..." [sic] category. The
results so far:

- KRotation doesn't work at all, but I don't get any error messages,
and `grep -iR krotation /var/log/*` doesn't give any results.
- KPendulum and Space work and are centered on the screen.
- All the others (Bitmap Flag, Euphoria, Fireworks 3D, Flux, Gravity,
Particle Fountain, and Solar Winds) use only the top 420 pixels of the
screen. It looks as though the graphics has been displaced, because it
doesn't look like it's been scaled to fit the area, and it also doesn't look
like the bottom 630 px (my screen is 1400x1050 px) have been cropped.

Searching Google and the KDE <http://bugs.kde.org/> and
x.org<https://bugs.freedesktop.org/>bug databases didn't produce any
results which seem related. Any tips?

Here are the relevant parts of my /etc/X11/xorg.conf:

EndSubSection
EndSection

Section "DRI"

Also, I use the following to enable the native resolution:
$ tail -1 /etc/rc.d/local
/usr/local/bin/915resolution 3c 1400 1050
