Problem: I bought this MBP second hand (MacBookPro 11,5 , 15-inch, Mid 2015) , and it works very nicely (smoothly running macOS Monterey, Windows 10 and elementary OS 7).
But I noticed after a week or three that a dark blotch have appeared in the upper left corner of the screen. It was not there the first few weeks (I know from pictures I took during my os install) and it does not appear to be growning.
Any suggestions to what may be the cause of this?
