Had anyone else had an issue where the screen coating on their retina display seems to be degrading in spots? To the naked eye, it looks like a minuscule chunk out of the screen, or a dead pixel, but upon closer inspection with the computer turned off, it appears that the coating has developed an imperfection in the finish, which is causing the refraction of light. I had the screen on replaced 5 weeks ago for the same issue, which had appeared in multiple spots. The computer is only 4 months old. Before that, when the computer was three weeks old, a bug crawled out from IN BETWEEN the pixels and the exterior coating and died, warranting the first screen replacement. This machine is already a replacement machine for an early 2011 MPB which had no end of hard drive problems. It would appear that any Apple product I own which is under an AppleCare warranty is cursed - my 2008 MBP and iPhone 4S are both out of warranty and doing just fine (knock on wood). Granted, AC has covered the repairs in all instances thus far, but really - what is wrong with Apple's quality control lately? I have never had this many issues with any of their products. Incensed, I've once again crawled through the forums, and this time found a few people with the same issue, as well as some other non related articles taking issue with LG vs Samsung retina displays. Could this be the source of the problem? Perhaps what comes OEM is Samsung and I've had two LG displays as replacements?? Apparently there is a third party script that can be ran on the machine to determine which manufacturer made the screen - but would this be accurate after two screen replacements? I'm seriously considering driving to Tampa to take care of this because I'm utterly embarrassed to have to ask my local service center/reseller to replace the screen on this computer a THIRD time in nearly as many months.
