We recently upgraded our project to Unity 5.6.4p2 from 5.6.1f1. We're noticing now when we toggle VRSettings.enabled from false to true the positional tracking gets really jumpy. Everything else in the scene is running at frame rate. Hands rendering from the avatar sdk, scene elements, etc. are all fine. But the tracking jumps around a lot at like 5 FPS.
Tried in an empty scene as well and we can reproduce.
We're not getting any errors so not sure what the source of this is. We've tried with Utils 1.24 and 1.26 and both behave the same way.
