[Camera rotating issue]

When I play, fullscreen. I got some serious camera rotating problems when I'm turning my character left and right fast with mouse it apparently turns 1080 degrees around and rotating like the mouse is out of control with berserker mode. Not kidding, anyone experienced the same problem or is it just me?

I used to have this when I played with my pentablet.

I stopped using my pentablet.

Try cleaning or replacing your mousepad.

my friend had this problem when he was using synergy (that program that lets you use 1 kbd/mouse across multiple platforms)

I found this to be a keyboard issue. When I changed keyboards, it stopped.

In the meantime, press a key in the direction of rotation to stop it. A for left, D for right. That would stop the spinning.
