It sounds like some events (or Bluetooth packets) are going missing. Please try a wired mouse, or try avoiding 2.4GHz wifi networks that may interfere with Bluetooth (use 5GHz instead).

I am not sure mutter is the correct package. I have a bluetooth mouse that works perfectly (I'll clarify below why I'm sure it works). Sometimes, seemingly at random, scrolling stops working correctly, but not always in all applications (eg. scroll starts failing in Firefox, but works fine in Terminal). When this happens, moving the mouse around over a window causes it to scroll randomly up and down, while moving the mouse wheel also works randomly (sometimes it scrolls in the correct direction, sometimes in the opposite direction, sometimes not at all). This occurs only when I have my external monitor connected (dual, non mirrored displays). If I unplug the display, the problem disappears immediately. If I plug the display back in, that problem reappears immediately (if it was already occurring before). While the problem is "active", I can scroll without problem using the notebook's touchpad. It seems to affect only the mouse. I've seen messages like this in the log, but it does not seem strongly correlated with the occurrence of the problem: libinput error: event21 - MX Anywhere 2S Mouse: client bug: event processing lagging behind by 21ms, your system is too slow Also, rebooting the computer fixes the issue for a few hours/days, until it appears again. Also, the problem sometimes "solves itself" after a few minutes, or it intermittenly appears every few minutes.
