Correction: MediaView now really works on Wayland!

At least under KDE / Kubuntu or Gnome / Fedora...

What was the problem? On Wayland, you can't get the absolute coordinates 
of a window (a "surface" in Wayland language). It's always (0,0).

I need that to position the surface that displays the video on top of 
the window (a "sub-surface" in Wayland language).

But...

Because of the marvelous invention of client-side decoration, the window 
contents is shifted, so that there is enough space for window 
decorations and shadows.

And, of course, you don't get that information the same way with GTK+ or 
Qt, and if you use different Wayland window managers!

At least now I successfully modified ScreenX and ScreenY properties so 
that it works on KDE / Kubuntu and Gnome / Fedora.

Please tell me if the MediaView displays videos correctly on your 
Wayland configuration.
