[Savage40] Small video glitches with savage snapshot

[bjorn+savage at update.uu.se]

Hi!

I downloaded and installed the driver snapshots

http://dri.freedesktop.org/snapshots/savage-20050314-linux.i386.tar.bz2
http://dri.freedesktop.org/snapshots/savage-20050404-linux.i386.tar.bz2

and compared to Tim's old 1.1.27t, the snapshots seems to introduce a
few new small glitches. I'll try switching back and forth between 1.1.27t

First, after running for a while, the top lines of video get garbled. 
Second, I get a weird pattern across the video window every now and
then. The garbled top lines are persistent, but go away if you, e.g.,
move the window. The pattern comes and goes, and seems related to
what's going on in other windows.

I can't seem to provoke the glitches, but if I just let the video
window run (while I'm doing things in other windows), sure enough, it
will happen.

Any idea what might be up? I'd post a screenshot of a window showing
the glitch, but naturally, all I get is the key-color... ;-)
