Garbled screen running Ubuntu on Sony VAIO PCG-748

[gypsy3001]

I recently installed Ubuntu 5.1 on an old Sony VAIO PCG-748. It's a
little slow, but still gets things done. I managed to get the system to
run at 1024x768 in 16-bit and 15-bit graphics mode. However, sometimes,
the middle of the screen gets garbled when displaying dialog boxes (see
photo below). Anyone know what's the deal? What are some fixes? Seems
that the video memory is corrupted or something.

That looks like something is overwriting parts of the video memory
used by those windows. If it happens to all apps, I'd suspect the X
server. If it only happens to QT based apps, as in the screenshot,
I'd be inclined to blame QT.
