I wonder if anyone ever had this kind of display issues on iMac? (Please see attached pics).
Details:
iMac 2017 27" i7 40 GB RAM
Bought late 2017.
The problem started after a year of use but it was pretty rare - a brief weirdness once in couple of months. (And since the iMac was already out of warranty anyway, I never contacted Apple).
The artifacts disappeared by themselves, or after refreshing the screen by switching apps or a doing a screenshot.
But recently it became a real nuisance. It can happen multiple times an hour sometimes affecting the entire screen, sometimes a single window. Especially when using Xcode but not exclusively.
The effects don't appear on screenshots so I had to take pictures of the Mac.
I did reset PRAM, which didn't make any difference.
I know I need to bring it to Apple for diagnostics for the exact answer. Still wonder if anyone ever had the same problems.
Thanks,
Leo
