Mouse hangs/freezes for a couple of milliseconds

Hello,


A few weeks ago i have upgraded from a late 2017 macbook pro touchbar to latest 16" model and from time to time, my mouse hangs/freezes for a very short time.

I don't see any particular pattern, just that from time to time the mouse arrow doesn't follow the trackpad action, so you'd start the action on the trackpad, then for a few ms the mouse arrow doesn't move, then it jumps right where it should be.


Any idea what could cause this, where should i start look at?

Best.

MacBook Pro Retina

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
