My Mac Mini M1 is OK, but there is tinted/black screen area
I was working on my Mac, but had to put it to sleep for 20 minutes to help my wife, but when I came back, it woke-up with a tinted/black screen area covering the otherwise no problem Mac.
I was able to do what I wanted, but could not see clear through this vail like rectangular area.
I started my other MacBook computer but found no real help or answer to this strange event.
I had shut my Mac mini and left it for some time, and came back to the problem, but it was gone and the Mac was working as expected, without hiding most of the screen in that TINT.
Before it come again, I like to know WHY and HOW TO AVOID such wires events on Apple computers?
I have the latest OS on my Mac, and this event was a little time after I had visited APPLE APP-STORE to get a free app.
Mac mini, macOS 14.6
