Strange Bloom/exposure/artifacts

I’m fairly new to Unreal VR, and I’m wondering if anyone has seen something like this before?
It does not show up in the Preview, and it does not help to rebuild the level. I’ve tried turning off bloom and auto-exposure in the project settings, and in the postProcessVolume.

The bug is different everytime too, even without changing anything. Also, sometimes when loading the playtest everything works perfectly fine.
