Here it is. I don't know on which update exactly this happened because I
usually do not use compiz/GL apps. But this laptop used to work very well with
compiz - i have demoed mplayer with video plugin for friends so I am sure it
The issue is caused by the kernel side, with the older kernel direct rendering
This works: Linux localhost.localdomain 188.8.131.52-137.fc8 #1 SMP Sun Feb 10

The latest update does not. probably the kernel driver side.
