Why VirtualBox window is transparent...

I have been using Compiz Fusion and VirtualBox for a while. They were both working well except I could not switch VirtualBox to fullscreen or seamless mode. I did not change any setting either in Compiz Fusion or VirtualBox, but these two days all black pixels have become transparent. What's the problem?... (If I shut down Compiz Fusion, VirtualBox displays coreectly.)

  1. I wish I knew - I have the exact same problem - the only reason I have Windows (on Virtualbox) is to view DRM videos in MediaPlayer - now I can't see the video - coz my Ubuntu wallpaper is all over it.
