I hate Gnome passionately. It is so bad I don't have words to describe just how had it really is.
KDE and Plasma suck almost as badly.
Wayland is still incompatible with some software and has been unstable for me in the past.

Having said that:
Xorg is still alive and (perhaps a little less) kicking and I would never want anything else than XFCE. I love XFCE. Xrdp should work fine with Xorg and XFCE.

Any other ideas? 😸

Edit:
Fixed it by removing xorgxrdp-glamor (I use AMD with open source drivers) and replaced it with the regular xorgxrdp-git version.
