[Quest 2] Videoplayer and RenderTexture creates white artifacts and stuttering when playing High resolution videos on Quest 2
Steps to reproduce:
1. Open the attached user's project "White-Artifacts-Bug.zip"
2. Switch to Android platform
3. Build for Quest 2
4. Move your head to the right to be able to see the Video
5. Move the HMD slightly left and right and observe white artifacts
Expected results: Videoplayer and RenderTexture does not create white artifacts and stuttering when playing high-resolution videos on Quest 2
Actual results: White artifacts appear when playing high-resolution videos in VR (See attached Example1.jpg)
Reproducible with: 2022.3.10f1, 2023.1.14f1, 2023.2.0b10, 2023.3.0a5
Could not test on 2021.3.30f1 due to scripting errors when downgrading
Reproducible on these devices:
VLNQA00415 - Oculus Quest 2 (Quest 2), CPU: Snapdragon XR2, GPU: Adreno 650, OS: 10
Reproducible on: Windows 10
Not reproducible on: No other environment tested
Notes:
-Issue reproduces with both OpenXR and OculusXR plugins (Issue is more apparent on OpenXR)
-Issue reproduces with Multi-view, Single Pass Instanced, and Multi-pass
-User notes:
-The resolution of the video influences the strength of the glitching. The higher the resolution, the more artifacts appear
-Changing the depth stencil format of the render texture influences the strength of the glitching
-Brighter videos seem to hide the artifacts, but the video still stutters
-Opening the Oculus home menu or starting a screen recording often reduces the issue

Resolution Note:
White artifacts are a known problem in Quest 2 rendering.
Stutter in video is due the headset's motion prediction to mismatched frame rate between the played content (25fps) and the headset (minimum of 72fps). The effect can be avoided by 1) having motion blur in the video and 2) rendering the video into the device's equirect layer, which bypasses motion prediction. This requires using Unity's latest Composition Layers package (the experimental version, as of this writing).
