Walking (Dark Souls 3)

Guys, I have a question. When you play on your controller and go to half stick (and not in front and to the side) animation of the character starts to twitch... it's hard to fully describe how it looks, but it looks like one animation cancels the other.

First I thought that the case in the grandfather zone, but no...
Actually, I would like to know if you have it and if not, what is it at me can be? in Google found nothing.
