Customers on both the MacRumors and Adobe support forums are reporting severe flickering when using some 2013 13" MacBook Air models when using Adobe Photoshop, particularly the larger brush tools.
Adobe representative Chris Cox posted on Adobe's support forums that he believes it is a driver or GPU issue, or possibly a problem with the LCD driver circuits. Additionally, he says Adobe has not been able to reproduce the issue, suggesting that it could be a particular run or series of MacBook Air models that are running into issues.
When we file a bug with Apple that we cannot reproduce ourselves: Apple ignores it.
Apple needs to hear from customers who experience the problem, and needs details on exactly which systems have the problem.
We will continue to research this, and if we find a system that reproduces it, then we can file a bug with Apple and have some hope that they might investigate.
Also, thanks for the video - that is definitely a driver or GPU issue, though with that kind of flickering I'd also suspect the LCD driver circuits.
New chipsets, like those in the new MacBook Air, occasionally have sporadic quality control issues. Some MacBook Air owners are reporting issues with Wi-Fi and Apple has issued a 'capture' order to Genius Bar representatives to take broken machines and send them to Cupertino for further analysis.
Adobe advises affected customers to contact AppleCare so the problem can be diagnosed and, hopefully, quickly resolved by Apple. Some reports have suggested that upgrading to Mavericks solves the problem, indicating a possible software issue.
