Camera sometimes starts at floor level - 2018.2.13

On launch, the camera will sometimes start at the floor level, i.e. y == 0.... This is inconsistent to reproduce but happens fairly frequently. Tracking wise, the device should be in a good state. When launching the app from the Windows cliff house, the tracking is perfect but as soon as the Unity app opens, the headset position is moved to floor level. This will sometimes resolve itself after a number of seconds, but not always.

I found a related issue (1001658) that says there was a fix in 2018.2, although the issues page doesn't specify a specific version. Is there a specific version which this fix was published in?

 

I do still see this in my project, especially when using the player. Unfortunately, I don't have a good repro case for filing a bug.

 

This happens sometimes with VR on 2018.3 latest also btw.
