Comment 2 for bug 149252

Hi, I can confirm this bug with the same graphic card (Intel 965GM) and with Ubuntu Gutsy on an HP laptop 6720s. When switching through windows, the first 2 or 3 windows switch correctly, then more TAB pressing results only in a empty screen, with the normal background and the reflection on the bottom of the screen.
There's a way to bypass the problem: deactivating the reflection this plugin works correctly, with no empty screens at all. Since I had no problems with cube-reflection or expo-reflection, I assume that this is a matter of this specific plugin, not of the handling of the reflection itself.
