I think this bug has become confused.

Compiz using high CPU when the screen is idle is definitely a bug and
should be what this bug is all about. But using higher CPU than idle
while moving windows or playing video are not unusual, because compiz is
the process responsible for rendering EVERY pixel on your screen. Compiz
is the compositor for Unity.

That said, I did create an experimental optimization for the compiz
"move" plugin the other day that more than halved the CPU while moving
windows. It's still experimental.

Please test my PPAs which contain proposed performance enhancements for
compiz and unity. Generally the Unity plugin is the largest contributor
to compiz' CPU...
