I have tried everything that I can think of, including every combination of WMR and StreamVR beta / non-beta, etc. I've seen a handful of people with G2 + WMR that have this issue and since I had it working with that same combo, but on my old rig, I think there is something environmental with this. It would be great if the developer could provide a fix, but I think there is something, maybe some conflicting software, driver or config that is the root cause of this since it's working fine for most people. It's a head scratcher, for sure.
