According to others that have/had this problem, Apple has a video driver update for MacBook that fixes this problem on Snow Leopard 10.6.4: http://support.apple.com/kb/DL1083 At any rate, disabling extensions also prevents the problem (i.e., the problem does not occur in Safe Mode).
Katy does the solution pointed out by Michael work ?
I have downloaded and installed the graphics update, but am still getting the artifacting. I'd rather not disable extensions. I only have the Australian Dictionary one, and the Compact Header one. Is there another solution?
I can only relate my own experience, which is that I only see the "artifacting" after I have clicked on the "More" link (to see more addresses) AND I have the "Compatibility Reporter" extension enabled (the only extension I have installed).
I don't have to click anything for it to happen... I can't make it STOP happening. :( Are there any reports I can send you guys, or test I can do, to give you more information?
The last update fixed this problem. Please close!
