Resolution Note:
Sorry if the last reply felt harsh, it was not the intention.
All I meant was that, since you seem to have a workaround already, there is no need to reopen the bug.
I invite you to use the forum instead the next time you need feedback or assistance. There we have better tools to communicate.
Bug resolution notes are meant to provide more context about why a bug is closed, and reopening a bug is usually reserved for cases where the fix has not worked.
I wish I had provided a better workaround from the beginning, but I'm happy that you have something working now.
I will repost the original resolution notes for future reference:
Flickering is caused by the particle having the same Lifetime as the particle system duration.
Depending on the framerate and the accumulated error, in can happen that for one frame the particle has died and the new one has not been spawned yet.
