Comment 62 for bug 320813

The third patch does improve things on Gigabyte GA-EG45M-DS2H mobo (G45), I can suspend/resume and VT switch without getting into that annoying >1sec freeze mode. I have not yet tried running xorg for a _long_ time to see if that still triggers the bug. glxgears now also reports around 60 FPS as excepted with vblank (the gears move now but they still flicker in a very annoying way, I guess this is a separate bug though). I can play chromnium arcade with nice FPS etc.

With 3-4 windows on each cube side the overall graphics performance is still _horrible_ when spinning the cube though. It doesn't stop for >1sec but it's embarrassingly slow for a quad core 2.8ghz, 8GB machine. If I _hold_ the "spin cube to the right" button for about 10-15 seconds then audio from totem is more or less certain to skip (silence for about 1sec) which is really annoying because it happens also sometimes on single normal ALT-TAB (not every ALT-TAB though).

G45 definitely needs some more love before it's usable. I will go test UXA now.
