    I am hoping too that this is fixed for built in as well, this is not just specific to urp

    Just to make sure, the fixes will cover the built-in pipeline as well?
    Tickets that have been marked as "duplicate" of this one, are referring to the built-in pipeline too.

    Also indeed the issue is related to GPU instancing somehow as I can confirm what SMEAS said.

    In my case I was able to get rid of the flickering by disabling GPU Instacing on the particle system.
