Comment 11 for bug 737454

Heres another datapoint for this problem. I was running 9.10 and switched monitors to a 1440x900 monitor and compiz started hogging cpu. So I upgraded to 10.10 but no joy. Googling around someone mentioned the same problem with a laptop and external monitor and that disconnecting wireless then reconnecting cleared it up at least for a while. So I disabled my wired connection, re-logged in and so far compiz is back down to 1% cpu. Since I know little about compiz Im not sure why it would make a difference but it sure did.

Maybe an strace of compiz would provide a hint.
