Bug Description
after resuming from suspend unity/ compiz feels like it renders much less frames per second. Moving windows around is very jerky as are the animations of the sidebar.
While moving around a window the Xorg CPU utilization spikes to 48%, so its eating up one of my 2 cores.
logging out and logging in again solves the problem. Switching to VTs however does not.
furthermore I got this on my kernel log:

kernel message was unrelated. Just checked with linux 3.1.0 from edgers ppa and there is no kernel message, but compiz is still sluggish.
