Here’s mine:
OS: Big Sur 11.2
CPU: M1
GPU: M1
Monitor: Dell 4K, connected via HDMI
Note: I’ve had success in dealing with this problem by power-cycling my monitor, as described in this thread: Mac M1 - Screen Freezes - Fixed by restarting monitor?
This solution doesn’t prevent the freezes but it allows me to recover from them much more easily than before, when I was rebooting to recover.
It’s also worth noting that I did not suffer from this issue AT ALL until I upgraded to BS 11.2.
