(Get the code!)
Same problem.
Using Ubuntu Gutsy (it was not there in Feisty)
NVIDIA GeForce FX 5500
It can be summarized as:
- Compiz disabled: some applications draw very slowly: qt-based, openoffice, maybe others. Video playback in totem and others is buggy: moving images seem broken by a diagonal line from top-left to botton-right and some other artifacts caused by some parts of the image been drawn before other parts. Specially visible in 1680x1050 full screen.
- Compiz enabled: now redraw is fast. Video playback in a windows seems ok, but consumes above 90% CPU in a AMD Athlon XP 2600. Video at full screen is also buggy, maybe becouse glx is disabled in full screen.
This issue makes video playback buggy at fullscreen in any case, and many applications to work slowly without compiz enabled. I think its importance should be more than "low".
