Steps to reproduce:
1. Create a new project
2. Enable VR
3. Create a particle system
4. Enter playmode and put it in your HMDs view
5. If error doesn't show, repeat Stop / Play of playmode again. (when doing this i can repro it with the MockHMD)

    ADNARO, yes this issue is probably the same problem you are seeing.

    Hi guys, just wondering if my issue fits into this category and upcoming fix or whether I should be looking elsewhere.

    I'm running a bunch of particle effects in VR and seem to have huge memory usage (~35GB) when entering playmode for the *second time after opening Unity* (first playmode attempt is really smooth).

    Profiler shows XR.WaitForGPU at ~150ms and under Memory, I'm getting the majority being taken up by GfxDriver.

    TBLANK555, the vertexBuffer error you have seen is part of the same problem and the fix covers it too.

    After upgrading my project to Unity 2018.3.3f1, I see this error spammed at runtime, but I also see this error spammed, which no one seems to have mentioned here:

    task.rasterData.vertexBuffer == NULL

    (Note: vertexBuffer, not indexBuffer)

    Is this error related to this bug? Does anyone else see the vertexBuffer error along with the indexBuffer errors?
