Windows 10. I can get the control/player app to work fine, but the minute it’s hidden or obscured, when I access it again, there’s a window frame but only blank white where the interface should be. It will continue the play if I set it to doing that.
Roon server is running on a QNAP HS-251, gigabit network. I had the twin Ethernet ports load balancing, but even with that disabled, I still have the issue. There is a fair amount of network traffic, but this isn’t just a slow or deferred redraw, it’s a never-happen.
