The problem arises from accumulated floating point error in the position properties due to the slight inaccuracies.

In Vision, there's no _great_ solutions for this.  
One option would be to use a script, instead of a binding, to update the angle. Immediately after updating the angle, force the position properties to the nearest whole number; that should prevent accumulating error (and thus drift) over time.
