I've had my 27" 2019 iMac for about a week now, and I've noticed a strange issue. Sometimes, at random, I notice the screen starts to flicker. I don't see any graphical artifacts or other issues, just the brightness flicker. It seems to be random and it comes and goes on occasion. Brightness level and temps seem to have no effect on it, it's completely random.
However, I have dyslexia and photophobia so it could very well be my eyes playing tricks on me. When I get a migraine I can see flickering in screens. My 2006 iMac shows flicker a lot too. Just wanted to see if anybody else has experienced this kind of issue, or knows what causes it. Since the process is so lengthy and I cannot easily do so for the next 2 weeks, I'd prefer to keep it if possible.
