    So Im getting this error:
    Assertion failed on expression: 'task.rasterData.vertexBuffer == NULL'
    UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

    Nothing really happens but it is annoying to keep getting this error in the console. Anyway I know this has been up before and I've read a lot but it seems like a kind of bug for over a year ago and should be solved? And it should be related to particle systems. I've never got this error before but when i implemented a line renderer it started to show up.
    No clue why but after a time studding it, it seems like the error only occurs when a particle system is doing its thing inside the lines of my line renderer. Someone who knows how I can solve this?

    yeah plz share your fix.....
    Same problem here.
    Not only with LineRenderer but also with TrailRenderer and only when these Components interacts with specific ParticleEffects.

    I can either turn the Line/TrailRenderer off and the Particle on or the other way around. Only when both are active i encounter the error....

    Really strange....

    I'm also getting this when using the particle system in 2019.3.0f6. Like some other people here, I'm also using both a trail renderer and a particle system - I had the trail renderer first with no problems, then the error started showing up when I added a particle system. I submitted a bug with a sample project.
