Comment 7 for bug 1036521

I don't think this is gles related.

The tool tip actually still looks there. And mine still have some transparency / blur, just not active.

if I mouse over a launcher icon to bring up the tool tip, then right click for the quicklist, you can see the tooltip underneath, but if i right click on the icon above, unity will close the open quicklist and open the new one, and for a brief moment, you can see the old tooltip still there.
