Q: OSX Lion, Graphic Artifacts

I have the same issue I only noticed it today for the first time. Im using a mid 2011 imac with 10.7.1

I have similar problems... Here's my thread just in case anyone wants to look at more screen shots.

I am taking my MBP to Apple certified company locally to get hardware tested as suggested by Apple. Crossing my fingers!

Sorry, I did not mean to link to my thread twice (I thought this was a different thread).

Well, looks like there is nothing wrong with the hardware of my Mac.

Apple tech folk suggested waiting for next Lion upgrade.

They also said that I could downgrade to 10.6.6 or 10.6.8 (even though my MBP came with Lion pre-installed... suposedly, the firmware on my MBP will jive with those older versions)... Of course, I will probably have a hard time finding an installer for those specific versions.

I hope Apple fixes this problem in the next release!

How did you manage to reproduce those artifacts?

They have another article written on the 18/09/2011 which states that Apple is aware of the issue: http://www.cultofmac.com/114446/apple-is-aware-of-imac-graphic-anomalies-but-no- fix-is-available-yet/

I accessed the first of those two and found it quite enlightening . . . The second then subsequenly the first I found I couldn't any longer  access . . . more enlightening!

anybody found solution???

yes, wait for the fix

are u sure next relese work?

nope, but we'll see soon.

My workaround is to simply add a second monitor via the mini display/thunderbolt port. I am unable the reproduce the artifacts on the finder window when the second monitor is attached. The moment I disconnect the cable, the artifacts come back.

I've had two monitors from the very beginning and still had artifacts.
