Also it seems like the pointer movement is jerky/laggy on my system. Clicking the correct button in DOpus is a bit of a challenging "game" lol. The mouse pointer on "Games and Applications" or in AmiBench when you navigate the F12 menu is smoother and has the hotspot in the right place.
I also have this. I tried different mice but it’s definitely laggy in AmiBench (and smooth in the Games and Applications front end).
