Hello everyone
I have a problem with kubuntu 9.10 with kde 4.3.4 which works great until I want to watch a movie with any movie player, when the effects-based composite are enabled, start to have those annoying vertical sync defects, but disappear when turn off the composite. This is striking because I've tried with other distros with kde 4.3.4, and this defect does not appear, so I suspect it's only a matter of configuration. I tried both with the original drivers from NVidia (v190.53 and v195b) as with those offered kubuntu (V195) and all these give the same result.
Details
Video card Gforce 6100. all options "Sync to Vblank" are enabled for both opengl and xvideo.
