I confirm also to have similar problems on my laptop.It's a Samsung P200 with an ATI X1250, the chipset should be the R600 chipset with installed Ubuntu 12.04 LTS.
In Unity I can see weird lines below the bar [IMG]http://i46.tinypic.com/2ur55yp.png[/IMG] [IMG]http://i49.tinypic.com/10hr30y.png[/IMG] and also I can see font corruptions on the bars of gnome-shell.
