This is an upstream bug, and it's been fixed in 13.1 so please either
install 13.1 or wait until Ubuntu updates fglrx in the repository (even
though they are practically the same -- minus a few differences -- if
you build them.)

Bug description:
WORKAROUND (1):
1. Open Catalyst Control Center.
2. Go to 3D > More Settings.
3. Set "Wait for vertical refresh" to "On, unless application specifies".
And if that doesn't work, then also do:
4. Run "ccsm"
5. In Workarounds, enable "Force full screen redraw (buffer swap) on repaint".
WORKAROUND (2):
1. Run ccsm (from package compizconfig-settings-manager)
2. In OpenGL > Sync To VBlank = OFF
TEST CASE:
1. Monitor compiz CPU usage (from /proc/<pid of compiz>/stat or top in batch
mode)
2. In "brightness and lock" settings set "Turn screen off when inactive" to 1
minute
3. Wait until screen turns off
4. Move mouse or press a key to turn screen back on
5. Check the CPU usage from the monitor
ACTUAL RESULT:
When screen turns off compiz goes to 100%
When the screen turns back on, cpu usage drops immediately to a normal value
The graph attached shows %CPU of compiz with a sample per second. The graph
has been captured on a system with a Radeon HD5770 and fglrx if that matter
