Bckground is corrupt (series of grey dots / lines). application windows for Chromium, AbiWord, Software Updater are all displayed correctly.

This is using a KVM Virtual Machine (Precise & Quantal releases do not exhibit this behaviour)

I have now run KVM with xubuntu and see the same video corruption.

I'm attaching a couple of screen shots.

I can also confirm that KVM installs CentOS 6.2 with no video corruption on the map page when you select 'where in the world are you'

Here are some screenshot's showing the graphical artifacts

This is from a raring host, running the 2012-12-13 iso

I have now had chance to install lubuntu-raring onto my dedicated server (CentOS 6.3). The video corruption is the same. As that is a different kernel & KVM install, it does look to be a problem with raring.

I was asked by ikonia on #ubuntu+1 to try a Ubuntu install on the KVM system that I have on my CentOS system. It has the same video corruption. This is from http://iso.qa.ubuntu.com/qatracker/milestones/243/builds/30504/downloads
