Bug Description

I was trying to figure out why the scale feature didn't show all windows when pressing super+w. I was on an empty workspace, summoned scale for all windows (super+w) and saw the window fading but no window previews appeared. I open CCSM an clicked around to check if the button bindings were set correct, and all of a sudden the system froze and compiz restartet.

Compiz crashed like this for me while fiddling around with "Animations" and "Animations Add On".
It was fixed by
$ unity --replace
