In the image above you see a MacBook Pro of the Apple company whose screen was left without a part of the anti-reflection substance with which it was treated from the factory, and this makes it extremely difficult to use in everyday life. Although they are sold all over the world at exorbitant prices, Apple's Macs have problems that should only be found in cheap products, counterfeited by a factory in China, but unfortunately many Apple customers have found out that they have to pay over $1000 on a Mac does not guarantee its quality.
MacBook Pros sold between June 2012 and the present have this problem with the anti-reflection substance that detaches from the screen, but of course not all products sold by the Apple company are affected to such an extent. Although normally problems of this kind can be found on small portions of the screen, some users claim that although they followed Apple's instructions for cleaning the screen, the final result is similar to the one in the image above.
I had the exact same problem, and I followed the cleaning instructions on the Apple website: a lint-free cloth and a small amount of water. Was trying to remove a mark in the corner of my screen and a shiny scratch appeared on the bezel. It grew in size and it looked like the coating on the bezel was coming off like everyone is saying. Started happening at the top of my display by the camera as well.
Although in most cases the problem is in the manufacturing process of macs and the Apple company replaced the screens of certain users for free, in some cases Apple employees stated that the defect is not covered by the warranty, the replacement of the screen in exchange for a few hundred dollars or euros being necessary. The problem started to be reported by users since 2013, but it has increased over time and now it seems that a very large number of users are reporting it with conclusive evidence.
Have you had a similar problem with a MacBook Pro?
