2. Enable VR
3. Create a particle system

5. If error doesn't show, repeat Stop / Play of playmode again. (when doing this i can repro it with the MockHMD)

    Yeah never mind my comment below. The issue came back to me. It wasn't for a while but now I see it again. Guess it's typical memory leak issue often not happening in the beginning...

    Would be great to hear what work is being done on the issue and the challenges it's presenting. The current lack of communication on this makes it seem like it's low priority, even if it isn't. Last we heard, 'a developer' was looking into it. That kind of sounds like a 3rd party although 'developer' could refer to an employee.

    Can we get confirmation that it's actively being worked on?

    Would it be possible to know if it is likely that this bug is going to be fixed within the next week or so? Otherwise I would start moving back to unity 2018.2 ?(although i really liked to new prefab system ...)

    Are the guys at Unity aware that this bug currently makes it virtually impossible to ship any VR game?
    Almost all games will use particle effects of some kind and this bug seriously worsens the experience because sooner or later the user will experience framerate drops that totally destroy the immersion.
