Tried using it on full brightness in a dark room on a dark background? There will be bleed. It's a manufacturing defect. https://forums.macrumors.com/threads/1114606/ I'm hardly the only one with it. I'm just doing something about it in contrary to ignoring it.
of course if you go into a dark room and put brightness up to full with a dark room there is a slight bleed, but this is an excessive test. it's not common use.
i NEVER said it didn't exist for other people who have it worse. all i said was that MINE was fine and yours sucks. Just cos yours and others is bad, doesn't mine is. i've tested it, i have no excessive or even noticeable bleed in standard use.
