When the stage views the stage is shown on are changed, ClutterStage currently provides a clutter_stage_update_resource_scales() method that allows invalidating the resource scales of all actors. With the new stage-views API that's going to be added to ClutterActor, we also need a method to invalidate the stage-views lists of actors in case the stage views are rebuilt and fortunately we can re-use the infrastructure for invalidating resource scales for that. So since resource scales depend on the stage views an actor is on, rename clutter_stage_update_resource_scales() and related methods to clutter_stage_clear_stage_views(), which also covers resource scales. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1196
Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
