[Problem]
Rendering corruption is seen in tooltips (see screenshots).  This was reported
by a user and reproduced by Jay who is one of the Unity/Compiz developers.

[Original Description]
Some lines appears above the tooltip when running Unity on an ATI gpu with the
open source driver. It does not happen with other GPU. The problem is random
and shows up on a few of the tooltips only. 
To reproduce, move the mouse over the launcher icons (to bring up the tooltips)
for a little while. It is best if you have many icons in the launcher. Shortly
after, some tooltips will exhibit the problem.
