Screenshot of full-screen VirtualBox VMs is shown after they are minimized

[qwach]

Happens with Compiz+Unity, but not with GNOME Shell. I haven't tested any non-Unity desktop enviroment that uses Compiz.

1. Start any VirtualBox VM and put it into full-screen mode (Host+F or menus).
2. Move the mouse to the bottom center of the screen so the VM menu bar shows.
3. Minimize the VM window from there.

The minimize animation will run, but neither the top nor the left menu bar will show. After that, a screenshot of the status of the VM at the time it was minimized will fill the whole screen. The mouse cursor will change according to its position in the now-invisible windows, but the screen will still show the VM screenshot until a window or menu is focused on by any means.
What should happen is, obviously, regular minimizing of the VM window.
