    @RICHARDKETTLEWELL

    Again, right at the top it says 'Fixed in Unity 2018.3' So, where can I download the Fix? Your answer is convoluted and does not make sense, First you say it's fixed then quote...'should be available approx 1st February. 2018.3 testing is still underway.'..

    And another update - the fix has passed testing for 2018.3.5 and will definitely be in that patch.
    Upgrade to that patch when it is released to get the fix. (hurrah!)

    Thanks again for everyone's patience and understanding while we fixed this horrible bug.

    The tentative release date for the patch is 6th February, though it might end up coming out a day or so later, depending on how smoothly our release cycle goes.

    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.
