I have the same problem (which seemed to begin a couple days ago), but I don’t think it has the same cause (I never cheer- I seldom have reason to ;) )
I have noticed two different types of mouse failures:
1. Mini-freezes that last less than a second. Motion control then resumes (but I am frequently dead by that point).
2. Longer freezes that completely lock up the mouse even after I minimize the game, and require a complete reboot of my computer.
I’ll post my system specs after I get home
