The size-change animation in gnome-shell needs to sync the window actors geometry during the animation, it currently does this by notifying the compositor that the animation was finished before it actually is. This causes a few bugs in Mutter though, since it will now emit the "effects-completed" signal on the window actor even though they aren't completed. To fix that, we need to decouple freezing and thawing of actor updates from window effects and allow gnome-shell to thaw actor updates before it notifies Mutter that the effect is completed. The first step for this is allowing to sync the actor geometry while an effect is active, this should be redundant since effects which actually need to inhibit those updates will freeze the actor anyway. Also a geometry change happening while another effect is active will kill the old effect anyway because MetaPluginManager kills all the active window effects before starting a new one; so the new size-change effect for any geometry change is going to kill the current effect. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1250 |

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.

The coding style used is primarily the GNU flavor of the GNOME coding
style
with some minor additions such as preferring stdint.h
types over GLib
fundamental types, and a soft 80 character line limit. However, in general,
look at the file you're editing for inspiration.
Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit.
