Screen becomes black after pressing dash or alt-tab

I did an upgrade from 11.04 to 11.10. Unity 3d becomes a black screen after pressing the dash-button or after pressing alt-tab to switch between open windows. I can see the panel on the top(lock,sound,..) and the panel on the left (launcher) but the rest is black.
It looks like a maximised black window. The open Windows are active but I cant see…
