I may have found a remote desktop solution that will work more reliably on my home network, it's called Rust Desk. I tried installing and using it on my existing remote desktops, but that would not work until I tried it with an old VM running Lubuntu. As that VM is running on a Proxmox node that seems to be having some disk problems, I built a new VM on my newest/fasted Proxmox host. So far I am happy with the result except that I can't seem to increase the resolution beyond 1920x1080. #

Found that if I set the display in Proxmox to VirtIO-GPU then I can increase the resolution and I have it set to 2048x1152, which is not the resolution I've been using for RDP and VNC but better than the above. I may fiddle with this more over time. I think 3840x2160 with a global scaling factor of 1.5 is just right. #

BTW, Rust Desk has a lot more options than any remote solution that I have tried, so there is more that I need to learn about. #
