OS X 10.8.5 Developer Seed May Fix MacBook Air Photoshop Flickering
It didn't happen with all units, but an Adobe representative said he believed it was a driver or GPU issue, and said Apple would need to fix the issue.
Today, a MacRumors tipster tells us the flickering issue has been fixed in the OS X 10.8.5 beta released to developers today. The bug made Photoshop nearly unusable for a number of MacBook Air users.
Some users have previously suggested that upgrading to the developer release of OS X Mavericks solved the problem, so the fix may be a matter of Apple pushing upgraded code sooner than it planned.
