Haunted by this problem to - Macbook Air M1 8GB with 4K external Monitor. Two things I am observing: a) Above 1080p + Overall Dark Screen content => The flickering starts - Setting system to light color scheme solves the problem for the time being b) HDMI and DisplayPort are exposed - can repro this with both cable types. Now I don't have Apple Care ... saved be some bucks ... but well ... How can I make Apple aware of this. The store can't do anything they blame my Monitor ... yeah like 3 Monitors which worked nice for years are suddenly failing. ( they work under Intel Macs so .. yeah )

Have the public beta installed right now - half an hour with no problems - that's new :)

It's back ... Set system to dark theme again ... went above 1080p .. @Apple - fix your shit!

Can anybody repro this with an M1 iPad? Maybe it's a hardware issue
