Comment 12 for bug 659816

Yep in the code there are matches for menus as well, but they seem to cause issues there and there. If the shadow clipping is done with a redraw as it is now, it's better not to clip at all.

This bug can be considered fixed when it behaves cleanly like mutter... at this moment, IMHO, it's better to revert or to remove the window class match.
