Well, it was bearable some time, while playing WoW, but not when watching Starcraft2 cinematics
It started happening very often on them or when you see the interface between missions(where they used the engine similar to cinematics). Very annoying
When you play the mission itself or a network game, the flickering is usual - it happens one time in a few minues or even a few tens of minutes.
Is there a way to track this issue - turn on some debug info in wine or driver or maybe mesa? Currently there is still nothing in dmesg, Xorg.0.log or ~/.xsession_errors.
