When in game my camera just randomly starts moving in a direction until I move the mouse and it then stops, sometimes I need to move the mouse three or four times before it stops still. I thought maybe my mouse was broken but if I open up menus within the game my mouse isn't actually moving. The mouse I am using is an old bog standard mouse but I was wondering, have I missed a setting within the game that would stop my mouse doing this, I can put up with it if needs be but it starts to get annoying as hell.
