The image of one of the eye is black when using XR "Stereo Display (non head-mounted)" with Unity 2019.2.0f1 + HDRP 6.9.1

1. What happened

When running a build of the project under Unity 2019.2.0f1 + HDRP + XR, only one eye (left or right) is displayed, the other one is black.

See the attached photo, where you can see a pair of 3D-active glasses with one black glass.

2. How we can reproduce it using the example you attached

- Open the attached project (the Sample scene) or create a new one (3D + HDRP)
- Check that HDRP version is 6.9.1
- Enable XR, set "Stereo Display (non head-mounted)" as device, and use the "Single Pass Instanced" mode
- Build and run it with a 3D capable device (we use 120Hz projectors)
- Notice that the image is black in one eye
