Having an odd mouse drift bug, a few degrees to the left per second. Not getting it in any other games or apps. Getting it even after restarting and uninstall/reinstall.
Only thing I can think of is that you might have a controller or other input device plugged in on your computer, since the game probably checks for both mouse and joystick input if I remember correctly. That’s a strange bug I haven’t encountered yet, I’m sorry it is causing you trouble with the game.
