My cursor just jumps around after mid-movement like every 10s. It isn't much, but say on a 13" screen, if I move fast, it can jump 5cm.
I use a Mac Mini M1 and Logitech G Pro wireless & MagicMouse (they both have the same issue).
I disabled the mouse sharing with my iPad, just in case that...
Mac 2011. 1tbhd. 16gb ram. High Sierra I think. Solid machine generally.
As you know this is super annoying.
I have cleaned track pad. Done that nvram hard reset holding option cmd and R and P.
Anything else I can try. I get around 2 min when log in and it just starts jumping and tight...
