I agree that this looks like a client side problem. But roonlabs is asking to troubleshoot this way and I am following their lead.
Perhaps they’re doing some remarkable server-side rendering and roon remotes are very thin clients. Or perhaps the client can send extensive debug logging info to the server when enabled.
The laptop is this Asus model. The desktop pc has a GeForce NVIDIA GTX 960 graphics adapter driving a 4k Dell monitor. The iPad is an A1566 iPad Air 2.
It even happens using remote desktop. Yes, Dorothy, I’ve been able to run the roon client over remote desktop, but you have to start it on the remote pc before opening remote desktop on a client. Here’s an open support issue that I submitted about this two years ago.
