What on earth have you do to the example to make a remarkable colour? Normally rain and snow and white/grey.. Also there is no motion blur effect evident which surprises me, is this with an extremely slow descent rate? > is that fixable without hacking away at the source? If you use defaults I can't believe you'd ever see artifices like these, the effect is so fast moving there is no way that one could pick it out without taking a screenshot. So for me I don't think there is an y issue, just stop messing around with it. As a more general statement, the precipitation is rendered in boxes that contain the particle quads, these particular are not depth sorted, but instead simply blended as the cost of sorting would be prohibitive, and the effect of non depth sorted is not normally noticeable. You can reduce some of the artefact's but double rendering. I may even implemented this at some point. But overall I'd say stop wasting your time on completely irrelevant stuff to your simulation, you will not see such subtle artifacts live.
