openSUSE Tumbleweed does not include the “Adwaita Demo” app, while its Flatpak that’s included with the “GNOME Nightly” repository gives me this error when trying to open it:
~> flatpak run org.gnome.Adwaita1.Demo
adwaita-1-demo: symbol lookup error: /app/lib/libadwaita-1.so.0: undefined symbol: as_component_get_developer
