I installed gnome-shell to check it out... and lightdm suffers from this bug so badly that I couldn't even select gnome-shell to log in with! lightdm shows the mouse regularly jumping to (and staying at) one of the four corners of the rectangle defined by the top left of the screen and the 'current' location of the mouse.

gdm suffers from the bug but works better than lightdm, and I was able to launch gnome-shell from it. gnome-shell does suffer from this bug, but IMO not as badly as compiz. Mutter feels much faster and more responsive (just try grabbing a window and moving it around with the mouse to see) than compiz in this VM, and this might have something to do with it.

Since this has only occurred since ubuntu and gnome-shell moved to use llvm-pipe, is there an llvm-pipe package that this should be assigned to, or is this purely a virtualbox issue?
