The behavior I've noticed occurs in complex scenes often, but also in the overworld. When it occurs, it occurs constantly and every second or two. A decent example of the severity would be in the Crypt of the Avatar, or the cave on the Shores of Malice - both scenarios had me struggling to control my character. I'd be heading one direction down a cave, and the next moment my character was facing the wall (during a turn). If it helps, I can provide a brief example video?
