The symptoms here seems kinda similar to Bug #969359. Was the fix to
this related to the gnome-settings-daemon?

SlugiusRex, no this bug is not related to gnome-settings-daemon. Only
the fglrx driver and compiz.

Ubuntu 11.10, again with gnome-shell.

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
I thought this was a compiz-only issue. Does anyone else have the bug
with Gnome Shell?

I have the same issue with catalyst version 12.4 (from the web site) and
HD 6850. The workaround did not work for me at all. I have the same
issue in Unity 3d and gnome 3. No issues with KDE (with compiz).

deactivating all vsyncing, both in ccsm + in amd catalyst makes compiz
snappier and less cpu intense for me ( hd 4650 mobility ).
The windows are tearing slightly when moving, but that is not a serious topic
when it comes to the overall desktop expierence. Unity already makes the cpu
more hot,
Workaround (Catalyst: 'wait...' + CCSM: 'force...' ) doesn't work for me.

The option Force full screen redraw (buffer swap) on repaint also
reduces the CPU usage with a NVIDIA Go 7700 (last driver version from
Ubuntu Package) on an Asus G1 laptop (Ubuntu 12.04).

Same problem HP dm1z-4100 (amd e-450)
Setting Force full screen redraw (buffer swap) on repaint seems to improve
performance overall, compiz normally uses 60-80% cpu when moving a window
(crazy right?) and when set Force full screen redraw (buffer swap) on repaint
it uses only ~30%.
