When moving the cube in Compiz/Beryl while glxgears or any other OpenGL/Video app is on screen, it doesn't move with the cube. It just stands there and flickers. Is this supposed to happen with fglrx 8.42?
It has always done this with the radeon drivers, but with XGL it beautifly goes along rotating with the cube. This also happens when moving its window.
Maybe unrelated, but some windows randomly turn white.
