It seems to be an issue with the room settings not initializing properly. We've seen it in Chromium & Firefox, both on Oculus & Vive.

On Firefox, even refreshing the page doesn't fix the issue, you must close the browser and re-open it. From our investigations it seems like the bad values are being reported by the browser itself, so I don't know if there is anything we can do on our side.
