Hm, yes, Wayland. It has not convinced me so I'm using X11 everywhere, that network transparency (through NX/X2go) is just too useful to let go. It is how my mother uses a Mate desktop running on the server-under-the-stairs here in Sweden from her laptop in the Netherlands to do her banking: Wireguard VPN + X2go. Would it work in Wayland? Probably, using VNC instead of X2go. Would it work without needing to futz with recalcitrant bits? Probably not. X2go "Just Works™" so... why bother?
