I had the same garbling problems with ATI Technologies Inc RC410 [Radeon Xpress 200].
First I've tried the Open source driver... It work but not fine because it was extremely brightness. I've activated restricted drivers and then I have the same problem (garbling) but everywhere (in desktop, when I scroll...). Then I see this bug report and I'am going to take a snapshot with ksnapshot... Impossible to do the snapshot because the snapshot was fine (without garbling)... But Surprise! Now no more garbling!! All works fine! Too weird for me... I don't understand nothing....
