Chardok glitchy movement (mouse AND keyboard)

[hextasy]

So in chardok on 1 character... I randomly turn anywhere from 30 to 180 degrees when moving... if I stand still, no movements - I'm good... If I move forward or backwards.... I'm good.... as soon as I use either the mouse, or keyboard to move left to right, there's a pretty good chance I'm going to do a sudden 180 degrees or more.

I have turned down spell effects, no change. I have turned OFF spell effects, no change. I am NOT playing on a potato (oc'd AMD to 4.2Ghz, Nvidia 970 OC'd as well, 16 GB RAM)...

And I repeat this only happens on ONE of my characters! No other characters have issues in this zone. Could this be a file/cache issue? something like that?

Thank you!
