--- Comment #31 from Lukas Kahnert openproggerfreak@gmail.com --- On my machine i have no flash player installed but it increase the chance for this bug too on watching HTML5-Videos(qtwebkit with gstreamer). Unigine Valley is always crashing with black screen and GPU hang. Unigine Heaven works but with white screen(the FPS are visible), but im not sure if it have something to do with this bug. Using Linux 3.16-rc4 and mesa-git
