[Chris Merrett <969860@xxxxxxxxxxxxxxxxxx>]

Well, for the time being I've switched from Unity to Unity 2D (metacity)
and I'm no longer having the issue at all.  Whenever I've seen the
problem compiz has been the only process hitting 100% when the screen is
off.  When the machine is left in this state for some time I sometimes
end up finding that the machine has hard-locked.

I've noticed that on occasion compiz hits 60-80% with the screen on too
when not much is happening.

Catalyst 12.4 (fglrx-updates) and AMD Radeon HD 5830.
