Default Re: VDPAU and KDE 4.8 compositing = slow

I have the exact same problem! The whole GUI stutters (like it's running with 30FPS), including the mouse. It only happens when playing a video while having the KDE desktop effects enabled. If I play a video and disable desktop effects while the video is still playing, then the problem disappears. It reappears again if I bring back desktop effects while the video is still playing.

The problem is not affected at all by PowerMizer. No matter if I force maximum clocks or not, the problem keeps occurring.

I have a GTX 560 Ti. It happens with both 290.10 as well as 295.17. I'm using Xv instead of VDPAU now because of this bug.
