The bug is still reproduceable with this patch,

It is noteworthy that the bug does not happen right away after starting compiz,
but anywhere from 30secs-1min or more of using the system before it starts,
then all windows are affected. For example on my system, I minimize all windows
except for ccsm, then click on a plugin, then back and do this several
different times and then the bug starts happening. It is important to not have
any damage happening in the background, such as anything animating, moving or
otherwise being damaged. Otherwise, you will never see the bug.
