[Daniel van Vugt <969860@xxxxxxxxxxxxxxxxxx>]

I can't reproduce this with intel graphics in 12.04.

jibel, could you please try ssh'ing into the machine when this happens
and getting a few stack snapshots of the busy compiz process using gdb?

This bug might be related to the buggy implementation of wait-for-vsync
in the fglrx driver. So please also try this as a workaround:

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".
