Resolved: MacBook Air 2012 owners _without_ this [image retention/text rendering] problem?

[GuidoH]

Last year I had a rMBP for a week or so, I returned it because of the image retention and a rendering problem in Safari, the rendering problem did only occur on the integrated GPU (Intel HD Graphics 4000).

Now I have a brand new MacBook Air 2012, which has the same GPU and, sadly, the same problems in Safari. It seems to me that it's a problem with the GPU driver or a Safari problem, but if that's true, all of you with the same MacBook Air should have this problem.

If it looks like this (the "O" in this case, but changes when resizing the window) you have the same problem:


Please let me know if you (don't) have the same problem!

Edit: I see the title is changed, I guess it's not totally clear. It's not about the image retention, just about the rendering. And it's not just text rendering.

Note: This issue has been solved in OS X 10.8.3!
