Desktop icons don't stay put after reboot


I believe I’ve been having this problem ever since installing Manjaro Cinnamon 2 years ago, and it’s finally gotten frustrating enough to seek assistance.

On most reboots, my desktop icons rearrange & stack up at random. Often it’s just a few than need to be rearranged, but occasionally everything goes haywire.

I’m looking for any suggestions anyone might have regarding the root cause, prevention steps, or a strategy for automating the cleanup process.
