Comment 13 for bug 1353675

Thank you. I wonder whether your flickering issue will stay fixed, as I can't think why a reboot would make a difference for VirtualBox (perhaps for Unity...) I suspect that the menu bar issue is because this is a generic Linux and not a specific Ubuntu build, but I suggest that that discussion move to our various communication channels<1> if you wish to continue it so as not to disturb the Unity developers.
