Public bug reported:

What happens:
On the normal login screen and thereafter the desktop the screen would flicker 
often when the mouse or windows are moved.

I use Ubuntu profile (not flashback like previous bug report - Please
see https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1250729 ).

Work around - sort of:
A way around it is to select Advanced option during boot and then recovery mode 
and then continue to normal login.
Then I don't experience flickering but also no gnome-panel and unity and dash 
and app Launcher. I have to start gnome-panel and any apps from Ctrl-Alt-t 
terminal.

info (from lshw) and what more can I give you?
