I think it is linked to cairo rendering as I have the same problem on the same computer when loading some pages in firefox (I had no problem before upgrade).
I have an ATI card too, but the problem can be reproduced with both fglrx and radeonhd.
On my other computer (nvidia gpu) I have no such problem.
