Some more data for your investigation. I've definitely been experiencing this problem, post Unity update. As another user mentioned, reducing the value in Advanced Settings for "Entity Animation Distance Multiplier" greatly reduces the impact of the problem, but of course now the game looks less lively.
I see the issue most often (but not limited) when entering Serbule Keep, especially in the trading area. Without using my keyboard (A and D to turn) I doubt I could navigate my way through there.
I'm interested in providing support in investigating this problem, as I am able to reliably reproduce it.
