While in many aspects this generation has improved the previous one, especially in autonomy, in others it seems that these Apple ultrabooks are accumulating problems. In the first moment it was the Wi-Fi outages that occurred in some concrete models of production and this time it's the turn of some strange flickers when using Photoshop.
Quite a few users have reported problems in Adobe support forums claiming that when using their photo editing software, especially when using tools such as brushes, the aforementioned flickers occur in some of these new Macbook Airs.
It is not yet known if the problem is something related to the Adobe software or GPU problems specific when situations such as those that Photoshop can represent. In Adobe they have already confirmed that they have not been able to reproduce the problem, so they believe that it may be something derived from a defective series of these teams.
We cannot reproduce the problem so far. (I think the problem only affects some batches of machines) We will keep trying, however. But without a system showing the problem, I can't isolate the cause. It could be the controller, the GPU (or VRAM), or the LCD display drivers.
The only recommendation from Adobe is that if this problem occurs, let's make the equipment warranty effective so it can be quickly diagnosed and resolved by Apple.
Among the different entries that users make, some of them have already suggested that an upgrade to the Mavericks DP2 It solves the problem, so although it is not fully confirmed, everything indicates that it is some strange combination of the Macbook Air hardware, the operating system and the editing software.
