Fresh install of Windows 10 Pro 20H2, have everything setup for passthrough (creating this topic on it now) and it works great. Decent game performance for an old Z97 i7-4790k with a RX 580 all running on a new install of Pop!_OS 20.10.
After installing all of the Windows drivers I installed the Looking Glass service and noticed that it was reloading, not a service restart, a few times a second creating dozens of tray icons. It doesn’t even get to the point where it can write to the log. I do see errors 1000 and 10005 in the event log. I’ve tried stable B2, bleeding edge, and some of the release candidates and I see the same behavior.
I also did a Windows reset figuring maybe some of the software I installed disagreed with it but I get the same behavior again on a clean install.
