Bug Description

12.04 Unity 3D in VirtualBox (guest additions installed) – 2 virtual monitors
ppa: lenses-testing

To test 12.04 multi monitor support I set up an vm with two virtual monitors. Since I started testing 12.04 (two months ago) the shadows start flickering (panel & top bar) when moving a window.

See attached video: 'shadow_flickering.ogv'
