I am not sure if my problem is related because I don't crash with compiz/unity but the ALT-TAB and virtual desktop switching is buggy. The ALT-TAB content appear slowly or the desktop switcher does not disapear and I cannot click any application. Sometimes it hang for 5-8 seconds. Somtimes the ALT-TAB switcher is semi transparent but wait 5 seconds before disapearing completely.
I lowered from 1920x1200 to 1552x864 and the problem goes away (at least with a couple hours test). 1600x1200 have the same problem as 1920x1200.
