In last dayz we get a problems (it seems like) - when you press F on waterpump or fire place, you'll get camera movements playing animation in 1st person.
That animations cause center of screen to move, and because pump/fireplace requires to see directly into model - its very easy to lost focus and break animation.

I think sameproblem happens when you start to any animation and try to see somewhere.... would be great to check by devs
