How to reproduce:
1. Open the attached project "PhysicsQuest_2020_3_4" from "JitteryPhysicsQuest.zip"
2. Build and Run on Oculus Quest 1/2
3. Observe the Scene in the headset

Expected result: The cube moves smoothly
Actual result: The cube starts off moving smoothly and eventually starts stuttering

Reproducible with:
Oculus XR 1.9.1 (2021.1.0a10, 2021.1.16f1, 2021.2.0b5)
Oculus XR 1.10.0-preview.2 (2021.2.0b5)
Not reproducible with: Oculus XR 1.9.1 (2020.3.15f1)
Could not test with: 2021.1.0a1 - 2021.1.0a9 (can not upgrade the project to work on these versions), 2022.1.0a3 (due to the case 1349162 issue)

Notes:
- This is not time.deltaTime. This is caused by switching the framerate during runtime
- Reproducible with Multi-Pass and Multiview
- Reproducible on Vulkan and OpenGLES3
- If the stutter is not seen sleep/awake the headset
- This does reproduce in the Editor using Oculus Link, however, it is not as laggy so for a clear reproduction building the project is necessary
