X11 applications will continue to work through XWayland.
I'm curious to find out how Kicad works with XWayland, given the dire warnings here: https://www.kicad.org/blog/2025/06/KiCad-and-Wayland-Support/
As it happens, I have a spare laptop with nothing to do (it's sound is broken but I don't think that's an issue for Kicad) so I may play and find out.
