I’ve never seen any sign of that on mine, and mine has the lid closed more than open. My original one was one that had to be replaced because of the smudged screen. When I checked the Apple Store display units, I didn’t see such an issue on any of them, so I brought mine that had been ordered online into the store and walked out 15 minutes later with this new one. I have seen no issues or encountered any issues of any kind since getting it last December. under good light conditions, then there is also nothing to see?
