My issue seems to be related. It seems that when enabling any Compiz plugin that requires a screen update, it corrupts the graphic of the upper panel (not sure what to call it in Unity since there is only one....and it's not really a panel) as can be seen on the attached screenshot. And the wobbling window effect shows teared movements which were not there before.
