This is my MacBook Air M4 which I bought last year in July. When I first saw this it was on my desk docked to my monitor.
this is not a software glitch as it didn't pop up on my monitor.
This remained on the screen for 10-15 minutes and then vanished and then appeared again later.
I have also been having some other display related issues which I had mentioned in a (reddit)previous post.
what could have caused this ?
a display cable or do I just have a faulty display?
