Beacon Beam working incorrectly.

Ever since the launch of mcxb1 I converted over my xb360 world, and since doing this, the lag has been real for me as the host. Also when the tu19/cu7 came out it became even more laggy, the beacons move very slow as apposed to creating a new world which moves just like the pc, this link shows what I am trying to say: https://www.youtube.com/watch?v=jC5SGfXGb_Q I have reported this bug many times on the minecraft forums but it never seems to get fixed. My friends also experience this lag when playing with me, and by lag I don't mean chunks not loading or blocks re-appearing when playing.
