X11 is a windowing system for Linux desktop.
Some Linux developers think it is outdated and problematic.
It has been around since day one but newer developers try to replace it with Wayland.
While XWayland is created to close the gap, I still experience a few times of compatibility issue when I login in a non X11 session.
First it was problem with JavaFX app created using B4J. However it seems it has been fixed now.
Recently I also tried to run B4J IDE on Linux desktop using Wine. I suspect the problem is also cause by Wayland. When I login in into X11 session, the problem is solved!
Recently there is a controversial about XLibre, a fork of X11 project.
Some Linux distro like Ubuntu and Fedora are starting to exclude X11 in the Gnome desktop by default.
My conclusion is, don't replace X11 with Wayland, which contains compatibility issue with apps that running fine on X11.
Until all the issues have been fixed.
