Comment 77 for bug 362359

@arnfranke
I just experienced it too last week. I'm using Ubuntu since 2015.
Current mouse (trackball) I used from the beginning of 2020. It works with no issue with Ubuntu 18.04. Issue occurred just after last Ubuntu update (middle of August).
Whats funny when I have my mouse/trackball plugged in I have this issue also with touchpad.
When I remove mouse USB - everything works fine again.
Another thing is that when I plug in other mouse or trackball - the issue is not present. It is just with single device.

I also tried with another laptop with Ubuntu 18.04 (without update) I worked on it 2 hours - there were no issues. Then I just updated Ubuntu and restarted that second laptop and... issue occurred also on the second machine and again just after Ubuntu update. I'm mad, I love to work with my trackball but I cannot now.

This behavior is so strange.

Also when I unplug my trackball and plug it agan it works fine for 30-60 seconds and then issue occurred again.
