Or, optionally, when the MUTTER_FRAMES_PLATFORM_LIBRARY env var is set to "adwaita". For debugging purposes, it is possible to disable loading any platform library with MUTTER_FRAMES_PLATFORM_LIBRARY set to "none". Add the CSS class "ssd-frame" to the MetaFrame (i.e. GtkWindow) instances as that lets libadwaita pick the right style, and won't do anything for non-Adwaita styles. This patch is specially careful not to link against libadwaita. Closes https://gitlab.gnome.org/GNOME/mutter/-/issues/2830 Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3981>
