I had some trouble with video tearing (using Nvidia GeForce 560Ti, with 310.44 nvidia driver), but could solve it by setting refresh rate from 50 to 120 in compiz settings manager -> composite. However, tearing is still a problem when watching flash videos. For example, the following video shows heavy tearing in fullscreen: http://www.youtube.com/watch?v=22ftfoCSPQI
When watching it using totem and vlc I have no tearing at all (I downloaded the video).
As suggested in many different other posts about this topic, I enabled VSync in compiz and nvidia-settings. Additionally, I enabled "prefer maximum performance" in nvidia-settings. Both without any effect.
I'm currently using chrome 27.0.1453.93 with flash plugin "Shockwave Flash 11.7 r700" on a ubuntu 13.04 64Bit machine.
Any suggestions, how to minimize tearing?
