When i move my mouse to turn the character, the view moves up to a certain point and only the head moves (looking around). The movement then locks at a certain point and you cannot turn any further, e.g. the body does not turn only the head.

This happens every time i start a game (stress test or offline) which means i can only run forward or backwards and strafe left and right.

I can normally fix it by changing a configuration setting and hitting apply. Does not happen in 0.62. Tabbing out of the game and back in does not fix it.
