Comment 0 for bug 848237

If I open some applications, if I minimize one it leaves behind an invisible window until I restore the window.

Steps to reproduce:
1. open firefox, evolution and rhythmbox
2. make sure they are overlapping in some manner
3. minimize rhythmbox
4. try to click in evolution or firefox where rhythmbox used to be. Focus is not changed and mouse clicks do not go to the window you are clicking on

If I click the rhythmbox icon in the Launcher (ie, unminimize it), then mouse clicks, etc operate as expected. This is not rhythmbox specific-- eg if I minimize evolution the same things happens.
