Comment 68 for bug 570151

My particular occurrence of this bug has nothing to do with virtual machines, it seems to be an X server or nVidia driver issue, since it even occurs at the login screen, and with any dm (lxdm, gdm, lightdm, kdm...). My mouse does not bounce between the two screens as in the videos, it "wraps around" the screen instead of going back over to the screen it came from.

The reason I think this is a similar bug is because it seems to be related to the nVidia driver, a multihead setup and problems going between screens. My particular machine has 24GB of RAM but I don't see any unusual memory usage when the mouse gets "stuck" in the screen.
