    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/

    This bug breaks the whole reason why the Allow Roll checkbox exists in the first place, this is bad!

    I also reported it, it has been reproduced and it's been sent it to engineering to get fixed.

    What is the status ?
    Will it make it into the 2018 LTS version ?

    Definitely! Still not working in 2018.3.6f1.
    Doing it with a MonoBehaviour is really slow.

    Still a pressing issue for AR/VR development.
