Billboard Particle System rolls in the Game View with "Allow Roll" disabled when a Camera is rotating around it
Repro steps:
1. Open user attached project
2. Enter Play Mode
3. Observe the Game View
Expected: The Camera rotates around the cloud without it rotating itself
Actual: The cloud rotates from time to time and only in the Game View
Reproducible with: 2018.3.0b2, 2019.1.0a1
Not reproducible with: 2017.4.11f1, 2018.2.9f1

I'm experiencing the same issue with particle rotation when tilting the HDM. I've added my vote to this issue. As the rest, I'm absolutely stunned that this hasn't been fixed in a very long time. If there is no fix, Unity should CLEARLY identify and document a work-around. Visual fidelity is key to VR experience development. Especially for those working to ensure content is built with quality visuals. Remove this issue and you will have opened a new set of creative possibilities for the VR developer community.

2019.1.14 and onwards, still an ongoing issue and still a major roadblock in our development.

Blows my mind this isn't fixed yet. Pretty much renders the ParticleSystem unusable in VR...

All the effort that Unity has put into VR... a VR editor even, but can't fix particle effects. Priorities. 8)

We are investigating ways to address this issue but it is not trivial, so a fix may not come in the short term.
For anyone hitting this issue, we advise reverting to the scripting method mentioned here: https://forums.oculusvr.com/developer/discussion/5998/hmd-roll-and-particles
If using Unity 2019, rewriting it to use the C# Job System with Burst will make it run very efficiently. Details on that API can be found here: https://forum.unity.com/threads/particle-system-c-job-system-support.529284/
