[XR][Post Processing] Ambient Occlusion effect moves when moving HMD and using Multi Scale Volumetric Obscurance

Package: PostProcessing


How to reproduce:
1. Open the 1150006-ReproProject Project
2. Open the Scenes/SampleScene Scene
3. Enter the Play Mode

Expected Result: Ambient Occlusion effect stays in the same place
Actual Result: Ambient Occlusion effect moves when moving the HMD

Reproducible with 2019.1.0a11, 2019.1.2f1, 2019.2.0b2, 2019.3.0a2
Not Reproducible with 2018.3.14f1, 2018.4.0f1

Note1: This issue appears to be related to the Unity Editor version and not the Post Processing package version
Note2: Could not test on earlier 2019.1 than 2019.1.0a11 versions because of compile errors
Note3: Scalable Ambient Obscurance is not affected

    I have this issue too with TAA in 2019.2.13 with UWP VR (w/ Mixed Reality Headset)

    Changing the AO mode on the Post Process Volume component from the default "Multi Scale Volumetric Obscurance" to "Scalable Ambient Obscurance" is a workaround in the meantime. Tested on both 2019.1.11f1 and 2019.2.6f1.

    I have reproduced this issue on Unity 2019.2.1f1 on the relatively new Postprocessing 2.1.7.

    Outside of VR, the effect works as expected:

    in VR, there are some obvious issues:

    Any progress or timeline on the fix? Thank you!

    This bug seems to affect TAA in VR as well, as was reported on the official GitHub repo:
