Just FYI, I run Roon core on a Linux box and never had any of these issues. Given how many streamers with Roon core built-in are Linux servers under the hood I would not be surprised if this was their most important OS.
I put Ubuntu server on an old spare Mac mini, and then installed Roon; it runs Roon solid as a rock. Agree 100% with @erik_squires that this is probably the OS they devote the most time and attention to. Much more solid than either Windows or Mac OS...
