Description Giovanni 2025-10-18 08:19:01 UTC
Hello maintainers,
I have successfully installed the yaru-theme package, and my GTK3 and GNOME Shell themes are correctly set to Yaru via GNOME Tweaks. However, applications built with GTK4 and Libadwaita do not adopt the Yaru-dark style. They use to the standard Adwaita/Libadwaita theme.
I attempted to manually force the theme by extracting the CSS from the gtk.resources file and placing it in my user configuration (~/.config/gtk-4.0/gtk.css), but this approach was not successfull

Continue in the Additional Information...

Reproducible: Always

Steps to Reproduce:
1.Install yaru-theme
2.Apply gtk3 and shell theme from gnome-tweaks
3.Opena a libadwaita app
Actual Results:
Libadwaita apps use default gnome colors

Expected Results:
Libadwaita apps use yaru colors like in ubuntu

Additional Information:
When using Ubuntu, some core Libadwaita applications (like GNOME Clocks or GNOME Tweaks) correctly applied the Yaru theme, so I thinks they use some patched libadwaita colors to follow system style 
Could you please provide guidance on the correct method to enable Yaru theming for GTK4/Libadwaita applications, or investigate why the installed yaru-gtk4-theme package is not being recognized?
Thank you for your time and effort in maintaining this package.
Best regards.
