@a6ff0b2b I have a SteelSeries USB mouse and a BT Logitech mouse connected at the same time. When multiple users are logged in the windows jump around with the USB mouse but not the BT mouse. Log the other user out and it goes away after a short while. M1 MacBook Pro on 13.5.2. So the issue could be USB mouse + multiple logged in users?
@ec93462c Yes, although not *all* USB mice. I have a Logitech USB mouse that does not exhibit the problem. What mouse are you using?
@a6ff0b2b all I have is 2 versions of the SteelSeries Sensei. Product numbers 62150 and 62155. All I can think of is a higher polling rate? https://devicetests.com/mouse-rate-test shows a max of 100hz for the BT mouse and 1000hz for the USB mice.
