Public bug reported:

I run Ubuntu 12.04 and use Gnome-Classic with the Unity plugin disabled.
I run a fully updated system. When switching between windows by clicking
on it with the mouse cursor, the window that is being switched to blanks
to white. This does *not* happen when using for example Compiz' Shift
Switcher or Scale plugin to switch between windows. This also does not
happen when using metacity instead of compiz (which is why I filed this
bug for the compiz package).

However, this issue does not occur when using the regular Ubuntu Unity
interface (selecting "Ubuntu" at the login screen). But Unity also uses
Compiz, so I'm not sure whether this is purely a Compiz bug.

I've attached a video demonstrating the problem.
