I have got following config: a notebook with GMA950 running Ubuntu 11.04 and an external monitor with 1920x1080 resolution connected over VGA.
With the previous version 10.10 I could run both screens flawlessly.
With Ubuntu 11.04 running dual screen produces a lot of artifacts, running on internal flat panel is OK.
Upon moving a window, the trail is not cleared; the background disapears, unity fails to return the dock.

The artifacts come with Gnome and Unity equally.
I suppose Compiz is the culprit...
