I have recently started playing with ubuntu 12.10 in as a guest image in VirtualBox. One of the problems i overcame was the desktop running slowly which is solved through installing virtualbox guest additions and enabling 3d acceleration in virtualbox.

The problem I now have is the screenshot function now only ever displays the background image like so: http://imgur.com/bDepk

When i turn off virtualbox 3d acceleration the problem disappears but the desktop becomes laggy again.

This appears to be a problem with unity 3d i think. Here is the pastebin of unity_test_support function: http://pastebin.com/wbsZsAHN

Here is the pastebin of the glxinfo function: http://pastebin.com/t0HUMKWC

Any help would be greatly appreciated!
