My first rMBP was experiencing ghosting and light bleed, so it was quickly swapped out for a replacement that appeared to be perfect (LG screen). However, in the last while, it's been picking up more and more image retention - until today, at which point it's hit a new extreme that even the first Macbook didn't show. I'm absolutely taking it back in to have it replaced again, as this is totally unacceptable. Since it's after the 14-day window by now, is it more likely that it'll be exchanged, or simply have the screen replaced? Has anyone else experienced this growing ghosting issue over time?
