White visual artefacts around borders of VR screen

We're encountering a bug in VR where areas of screen around the frame being rendered in the headset are white.

This is visible inside the headset and particularly inside the Oculus Rift CV1 where it's easy to see past the borders of the rendered frames on the screen.


This for us under the following circumstances:
- using 2019.2.7f2 (though I recreated it in 2018.3.0f2)
- using the Oculus API for VR,
- Single pass rendering
- Deferred rendeing pass
- using Post-Processing 2.1.7 from the package manager
- Post-Processing is setup and enabled on the VR Camera
- Eye adaptation is enabled in our Post-Process profile
- Minimum EV is set to -1
- Camera is looking at an area in the scene forcing eye adaptation to brighten the view.

Does anyone know a solution or work around for this issue?

 

Hi, we're using Unity 2021 and it still happens. Did you find any workaround?

Thanks
