RS Distorted aiming(iron sight/scope) while moving

I've searched for this issue but I could not find anything similar and I don't know if anybody have this problem either.



The problem happens when I press to aim(mouse right-button) while moving(while sprint or not) and stops, the aim become distorted. Don't happens always, only sometimes, so I can't reproduce anytime I want, but it happens often.



See the screens below:











Then, when this happens, sometimes if I just move the aim around, the aim centers by itself, sometimes don't and I have to move aiming. If this still don't fix the aim, I stop aiming, move and I try aim again.



I don't think this happens on RO2 too, so I tagged this as RS only.
