Keep in mind that the current XWayland is very barebones and there are many improvements planned like glamor support direct rendering etc. So I would expect quite a lot of improvements still for mutter as a wayland compositor and xwayland. Very surprised that theming etc. works great already. I can launch the xfce terminal which uses XWayland and it still has the proper theme applied.
No announcement yet.
Wayland 1.5 Appears To Be In Great Shape
