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.
