    Ok, I see how this goes. The thing with some particle effects (like fire) is that their size is variable since the emitting is somewhat random, and that makes that, sometimes, the particle is on a corner of the screen and its bounding box can for a few frames be small enough to get out of the camera frustum, and then get in again. In the frames in which the bounding box is smaller and it's not inside the screen space, the particles are culled and, as soon as the particle grows bigger and the bounding box expands, the particle appears again.

    It's apparently related to the subemmitters. The Yscale value in their transform must be exactly 1, don't really know why.

    This also happens with sprites too (although in that case setting their Zscale to a very very small value such as 0.001f kind of solves the issue).

    Hoping this will be fixed soon since it clearly affects the visuals of any game.
