"World to Meters Scale" node broken?

Hi!
I’m trying to scale up and down the player in VR depending on the distance of their hands using the node “World to Meters Scale”, which is supposed to change the world’s scale instead of the player (if I understood that correctly). It works, but it starts to flick a lot and I don’t think it’s a logic’s error, since I’ve tried multiple ways of doing that (I’m doing it on Event Tick through a boolean to control it) and all of them cause even a small flick after some time, is there any way I can use it on Tick without causing it to flick?
