Contrary to my earlier instinct, it appears to happen independently if you hold the movement or not. Keep in mind i am at all times doing a uniform movement from side to side with the mouse.

Edit: if you're unable to reproduce, it might just be the case this affecting my own config only, in which case:

But please, don't bother too much with this, i know you have higher priority stuff in the pipe.

Thanks again.
