Mouse lagging on m1 max bbp

You've depricated this message and I can't reply on it, but exactly this: Lagging mouse on Mac Mini M1 - Apple Community

Another case thats weird:

I open chrome or safari > Open outlook.com > hover mouse on mail-list > Mouse cursor moves fluid but it highlights the mails on hover only when i stop the external mouse, when I use the trackpad it highlights straight away. As if macs visible cursor is another entity from the actual behaviour...

It has worked before. It stopped working in the last few weeks without any new software from my part except for updating macos to the latest version.

It's not the USB-dongle or ports unless all three ports just got broken.

The solution can't be to turn off wifi all the time.

Wired USB and bluetooth both lags.

Computer is pretty much idle. Same issue regardless of charging or on battery.

It's _a bit_ more prominent when screensharing in zoom and discord (and only screensharing, both programs work flawless otherwise)

Any external mouse always lags. Trackpad always works as intended.

I'm not alone and more has this problem, but can't find an answer on this that helps me. So help please! :)
