> gtk4-demo-application is giving me one empty icon which seems wrong

Weird. I can reproduce that, it should be loaded from the embedded gresource:
https://gitlab.gnome.org/GNOME/gtk/-/blob/main/demos/gtk-demo/demo.gresource.xml#L430

Edit: I found the issue:
https://gitlab.gnome.org/GNOME/gtk/-/blob/main/demos/gtk-demo/demo.gresource.xml#L413
https://gitlab.gnome.org/GNOME/gtk/-/blob/main/demos/gtk-demo/application.c#L543

(`/org/gtk/Demo4` vs `org.gtk.Demo4.App`. Replacing `org.gtk.Demo4.App` with `org.gtk.Demo4` causes it to work)
