Chromecast ultra 4k displayed multiple times in displays

A well known problem -

Duplicate displays

@noris - Did you ever solve this? I ask because since I’ve switched to running ROCK, I have the same problem. It seems to increase over time or over ROCK startups, maybe. I originally had two now I have three. Nothing changes on my system. I just switch my core from WIN10 to ROCK (two different machines) and back, etc. If I delete the duplicates and leave one, then they all disappear and Roon complains it can’t find any displays. Doesn’t really affect anything, just a odd bug.
