[XR SDK] Multiple viewport rectangles does not work

Package: XR Management

-

Reproduction steps:
1. Open the attached project ("MultipleCameraTest.zip")
2. Open the "No-VR" scene
3. Enter Play mode
4. Resize the Game window

Expected result: Viewports displays different images, does not glitch when resizing
Actual result: Viewports display the same image, glitches when resizing (see "fPgmt1nUCP.mp4" video)

Reproducible with: XR SDK 3.2.17, 4.0.0-pre.3 (2019.4.19f1, 2020.2.3f1, 2021.1.0b5, 2021.2.0a3)
Not reproducible with: 2018.4.31f1 (XR SDK not available)

Tested:
- Oculus Rift S
- MockHMD

  1. Resolution Note:

    The XR SDK Devices provided by Unity only support a single viewport when rendering to eye textures. Support for multiple viewports either requires rendering into a render texture and blitting the results in an additional pass, or authoring a custom XR SDK display provider.

    I worked around this problem by using the "Forward" rendering path and turning off HDR and MSAA. The viewport rects work as expected if using these configurations.
