Current prerelease is 1.2.5
1.2.4 is the first to introduce experimental Wayland support. Especially on KDE Plasma there are supposed to be some issues.
Lets test!
Why?
Regular RDP/VNC programs are hard to use in real scenarios, as they rely on IP addresses. RustDesk is easier as it uses a Rendezvouz server that can also be selfhostet or reimplemented.
Not recommending against RustDesk - it is a very cool project - but regarding the “Why?”, you could use a VPN or something like Tailscale which has MagicDNS that’ll resolve hostnames of computers to their local IP address. You can use this with GNOME’s RDP server to remote in from another device pretty easily.
this kind of software is mostly used for tech support, so your option is too hard to setup
