As for Wayland, it does not support setting the opacity of a specific 
window.

In that case, QT5/QT6 prints a warning message saying that the feature 
is not implemented.

And GTK+3 emulates the feature by drawing all the widgets of the window 
with an added transparency. Of course, when CSD is disabled like with 
KDE window manager, the title bar stays opaque.

Is there any X11 useful feature that is fully supported correctly by 
Wayland? I still can't use it, even with KDE. Everything almost works, 
except the several X11 unsupported uesful features, but things are 
slower (on KDE / Radeon integrated CPU), especially the games.

It makes me sad. But maybe the reason is that I don't work with three 
different high-resolution high-frequency huge high-dynamic range 
screens. Just a unique normal 1920x1080 60hz screen.
