Public bug reported:
Compiz CPU load is about 8% when system is idling and the screen is on.
About 30 seconds after the screen goes blank the CPU load increases to
100% and remain at that level until keyboard or mouse activity enables
the screen. At that time the CPU load returns to 8%. The system gets
very hot and the fan is running at maximum speed when the screen is
blank.
Problem came after upgrade from 11.10 to 12.04. No problem if using
Ubuntu 2D mode.
