[OpenXR] Editor performance drops extremely after HMD becomes inactive using OpenXR due to GFX.WaitForRenderThread while in Play Mode
Steps to reproduce:
1. Open the attached user's project "XRPerformance.zip"
2. Connect the Oculus link to Quest 2
3. Make sure OpenXR is selected as the XR Plugin
4. Open the Profiler
5. Enter Play Mode
6. Observe the Profiler while the headset is active (press a finger over the sensor)
7. Dismount the headset for it to become inactive
8. Observe the GFX.WaitForRenderThread in the Profiler climbing rapidly when the headset is inactive
Expected results: Editor performance does not drop extremely after HDM becomes inactive using OpenXR due to GFX.WaitForRenderThread
Actual Results: Editor performance drops extremely after HDM becomes inactive using OpenXR due to GFX.WaitForRenderThread
