Bug OpenXR - Valve Index - Controllers missing (no device)

We are getting reports from users of valve index players having an issue where there are no controllers present. We aren't sure what's different since most players have no issues. We iterate through all the devices and print out what the system reports, and there are just no controllers being reported. It's probably only 1 in 250~ users, so it's not very common. They all report that the controllers have no issues in any other game.

Anyone seen this, or have any idea whats going on?

Code (CSharp):

1. Device Name: HeadTrackingOpenXR
2. Device Display Name: Head Tracking - OpenXR
3. Headset OpenXR Name: SteamVR/OpenXR : lighthouse
4. OpenXR: device 0: Head Tracking - OpenXR
5. OpenXR: node Head found x1
6. OpenXR: node Head-0: Head Tracking - OpenXR
7. OpenXR: node LeftHand found x0
8. OpenXR: node RightHand found x0
9. OpenXR: node TrackingReference found x0
10. OpenXR: node HardwareTracker found x0
11. OpenXR: found 1 hmds
12. OpenXR: hmd 0: CameraPose (device: XRInputV1::OpenXR::HeadTrackingOpenXR:/HeadTrackingOpenXR, valid: False)

 

This is the setting causing this - it defaults to on and turning it off fixes the issue.

SteamVR Settings -> Video -> Pause VR when Headset is Idle
