So, I went to the Apple Store yesterday to check out the new Retina MBP. It was very cool. While I was there, I also took a look at the new Airs and 13" MBP, which I was possibly interested in buying at some point in the next year. I immediately noticed that on all the machines that relied exclusively on the integrated HD 4000 graphics processor, there were graphical glitches/errors present when switching spaces using a 3-finger swipe in Finder. It was as if it couldn't properly handle the animation. It's hard to describe, but it was plainly obvious. I tried it on the 11" Air, the 13" Air, and the 13" MBP, and they all had the exact same problem. The 15" MBP and the rMBP did not have the issue at all. My 2008 13" Aluminum Macbook does not have the problem, nor does my 2007 Aluminum iMac. I hope it's possible that the issue can/will be fixed via a software update. I searched online and couldn't find any other reports of the problem, which I found very surprising. Has anyone else noticed this? I wouldn't buy a computer with this problem because it would definitely bug me.
