Hey guys,
I'm having an issue with video glitching after resume. Basically after resuming and unlocking the screen, I get corrupted video pages swapping in with bits and pieces of the unlock screen flashing in and out.
If I kill and restart X I get the same problem, but if I start cinnamon instead of xfce it seems to clear up the problem, even if I startup xfce again afterward. I've tried toggling the compositor on and off when the issue happens, but no luck. The only way I can fix it is to either start cinnamon or reboot.
I was thinking the problem was SNA vs UXA, but I can't seem to get UXA enabled even by sticking the relevant option line into the xorg conf directory.
I'm running arch on a MacBook Air 13" mid 2011.
Any ideas?
