Floating windows, UI implementation, and compositor improvements for the new COSMIC desktop environment.

Notable changes:

  • Tracking improvements. For example, if you use the launcher to launch an application and then switch workspaces, it will still launch in the workspace you opened it from;
  • Supported the ext-session-lock protocol, which authenticates the user and informs the compositor when the session should be unlocked
  • XDG activation and DBus activation support
  • work on HDR
  • Ongoing work to package COSMIC on NixOS: tracking issue

    Well GTK does not have theming anymore, though it still needs some way to configure fonts and icon theme.

        Iirc Gradience punches a hole in the flatpak sandbox for xdg-config/gtk-4.0, which usually is in .config. This makes it work and isn’t a security problem.

        Gnome Shell is unaffected because it doesn’t use GTK.

            It uses a custom UI framework, St, using renderer primitives built into the compositor, mutter. Whereas COSMIC is using the same libcosmic library inside the compositor, applets, and desktop applications. Thanks due to our Smithay client toolkit being used to provide a renderer for iced which supports the Wayland layer shell protocol.

                Yes, this can already be seen when configuring a personal theme in the Desktop > Appearances page in COSMIC Settings. Compositor elements, applets, the login and lock screens, and COSMIC applications automatically adjust in realtime to the configuration changes.
