Public bug reported:

Steps to reproduce bug:
1. Open any app and maximize it
2. Minimize it with minimize button, wait for animation to finish. Click on launcher to restore that app. Everithing is OK
3 Minimize app and while minimize animation lasts click on the launcher to restore app. Window restores to maximized state but is blank (white).

You can return contents of window by:

1. Double clicking on panel
2. By repeating action which makes things disappear (step 3 from above).

I have duration of minimize and maximize animations set to 400 ms so it's easier to reproduce bug if animations last longer.
After reproducing bug and closing that window (or soon after) compiz often crashes and I get this bug report:

In the attatchment is clip which shows all described above (sorry for
bad quality, but you'll get the picture).
