I tried to reproduce this on a recent artful install and failed; but I think it's at least worth keeping an eye on, given the move to Gnome Shell and using the Ambiance/Radiance themes there. To me, it seems like it's likely video corruption specific to the driver and exact video chipset, but if someone got this, others might too.
Can you reproduce this on a live session from a daily image[1], using "Try Ubuntu before installing"?
