A similar issue happens with Apple Silicon macs and external monitors since long time ago. A fix I found online [1] is to disable GPU dithering using the Better Display app.
The flickering was so bad in my case that the pixels got stuck for some minutes when it happened.

- ProfessorLayton 8mo agoI tried that and many other things like changing the default color profile and it and it didn't work. A reboot fixes it for a few days before returning, so it definitely seems like a bug rather than a hardware issue. Both my work MBP (No issues, macos 15) and personal Air (macos26) are apple silicon.
