Fucked up mouse/trackpad

When I play GMod on my laptop using the trackpad, it starts out spinning like mad, then it slows down eventually but then the movements are really weird. The only way I can describe it is like those golf arcade games where you push the ball and it accelerates and stuff. The mouse doesn’t move it accelerates.

I’ve toyed around with the mouse settings to no avail.
Also, reinstalled.

what do I do? :v:
