    I didn't have any luck with single pass either.

    Just updated to f3 and this is popping up in our VR project. We are rendering using Single Pass Instanced.

    I did a lot of testing regarding this issue and my finding is that if you can try switch to "Single Pass" instead of "Multipass" in the XR Settings. This seems to fix the bug.
