As explained in the title .. it started happenning since installation of new openSUSE and it looks quite bizarre, see below for a shot from blip.tv.
It happens usually after few minutes of watching a video, sometimes sooner, sometimes later. It happens also on Youtube. Any ideas? I would like to retain hardware acceleration so I do not accept solutions disabling it.
To add more details about my setup. Laptop is a Thinkpad T420 with NVIDIA Quadro NVS 4200M, hooked up to double monitors via docking station.
