Ubuntu 8.10, KDE 4.2 (with compositing enabled), nvidia 8600 GTS, drivers 180.22.
It happens once in a while in kaffeine (xine), or even in flash video in firefox. Most of the time it works properly though. Anyway, I should try to disable compositing, as the 3D display gets very slow after launching & quitting a 3D app (like world of goo or any other game) when compositing is enabled...
Try with the latest driver. If it still doesn't work, please provide a bug report.
