Hello,

currently, I'm testing Ubuntu 11.10 in Virtualbox 4.1.4.
With Ubuntu 2D everything works fine, but I've got window problems in Ubuntu default with 3D support.

Login works fine and I see the desktop and menubar. But if I start a program i can't see the program window.
I see the updated menu bar with the menu functions of the running programm but no window visible.

Is there a compiz problem with virtualbox?

Thank's for your help...

Stephan
