When hotplugging a new monitor, we recreate all the MetaWaylandOutputs and need to emit leave events to the surfaces for the old wl_outputs and enter events for the newly created ones. There's a race condition though: We might update the monitors a surface is on (and thus emit enter/leave events for the wl_outputs) before the Wayland client is registered with the new wl_output (ie. the bind_output() callback of MetaWaylandOutput was called), which means we don't send an enter event to the client in surface_entered_output(). Since MetaWaylandSurface now has the MetaWaylandOutput in its outputs hashtable, it thinks the client has been notified and won't send any more enter events. To fix that, make MetaWaylandOutput emit a new signal "output-bound" when a client bound to the output and make all surfaces which are on that output listen to the signal. In the signal handler compare the newly added client to the client the surface belongs to, and if it's the same one, send an enter event to that client. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1230 |

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.
