At random times, there is a red discoloration in the corner of my screen that varies in size from nonexistant to stretching across the right edge. It is similar to the following thread except that thread mentions the whole screen and my issue only covers a single corner: MacBook Pro display suddenly has a very faint warm/pink tint
A couple of observations I noticed was that when you take a screenshot, the discoloration is not in the screen shot. When I physically press the cloud with my finger, it goes away for a short time but comes back.
Does anyone know what is going on and what to do about it?
