[Bug]: Performant messes with positioning logic/delta movement

[RaveTr]

Describe the bug you're experiencing

The following code experiences logical errors when Performant is installed:

	public boolean isStuck() {
		double dx = getX() - xo;
		double dz = getZ() - zo;
		double dxSqr = dx * dx;
		double dzSqr = dz * dz;
		
		return dxSqr + dzSqr < getMovementThreshold();
	}

	public double getMovementThreshold() {
		return 2.500000277905201E-7; // Default (arbitrary) value used by vanilla's movement controllers
	}

dx and dz fluctuate dramatically with Performant installed. Is there a known workaround?

Reproducability

• Download Performant.
• Use any mod whose animations (or other client-side aspects) depend on movement.
