I am working on my M1 MacBook Air, plugged in via USB-C (DP-ALT) and the resolution keeps changing slightly on both my external display and laptop display. It's like the two browsers I have open and PhpStorm are being moved about 30 pixels or so, back and forth, fairly regularly. I have never experienced that before.

I have noticed with 11.6, sometimes I have to plug in the USB-C cable a few times before it will finally work with the monitor when not in clamshell mode.

I wonder whether it has something to do with the battery which says On Hold 80%. Like it's switching between power and battery and for some reason altering the display?
