I upgraded my late 2010 MBA (MacBookAir3,2) to Mountain Lion 10.8.3.... awake from sleep, and I get a horrible screen flicker, every few seconds. This happens both during the login screen and when logged in.


It is awful, it is almost completely unusable. I have been very happy with my MBA since I bought it 2.5 years ago, was thinking of upgrading in a few months, but now seriously reconsidering. I am losing quite a bit of work this way.


Can anyone help? Apple rep or community member? Please? Desperate here....

MacBook Air, OS X Mountain Lion (10.8.3)
