Normally we bail out in `sync_actor_geometry()`. The comment there states: ``` Normally we want freezing a window to also freeze its position; this allows windows to atomically move and resize together, either under app control, or because the user is resizing from the left/top. But on initial placement we need to assign a position, since immediately after the window is shown, the map effect will go into effect and prevent further geometry updates. ``` The signal for the initial sync originates in `MetaWindow` though and predates `xdg_toplevel_set_maximized`, which again calls `meta_window_force_placement`, triggering the signal too early. As a result, Wayland clients that start up maximized have a wrong map animation, starting in the top-left corner. In order to fix this without changing big parts of the geometry logic and risking regressions, force the initial sync again before mapping. Solution suggested by Jonas Ådahl. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1164 |

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.
