Lance, what is the spec and age of the machine this is happening with. And is the machine hanging (unresponsive) or just a local issue but still useable from another remote? It helps narrow the problem down so help can be better targeted. My laptop (AMD A8 remote only) occasionally white screens but the resize button fixes it.
I have had what might be the same problem with a Windows 10 machine, it often occurs when Windows upgrades itself. I believe there is an issue with a particular Intel Graphics driver that upsets Roon. I can invariably fix the issue by going into Control Panel > System and Security > System > Advanced System Settings > Performance Settings > then pick either “Let Windows choose … “ or “ Adjust for best performance” such that you are flipping from whatever it is to the other one. Then OK your way out and reboot and Roon should be fine. You can flip the setting back and Roon stays OK. Fingers crossed this has worked for me since I first had Roon, but the original white screen was heart stopping.
