Some clients like X11 LibreOffice clear the selection prior to copying some content there. This selection clear is correctly seen by our clipboard manager as a hint to take ownership and preserve the last copied content, all while LO is issuing other XSetSelection with the new clipboard content. Our use of META_CURRENT_TIME turns this into a race condition, as there's both LO and our clipboard manager trying to do XSetSelection(), from our side it's all up to the order in which the requests arrive to the X server. In order to break the tie, keep the selection timestamp from the XFixes event (i.e. the timestamp set by the XSetSelection external call that is unsetting the clipboard) and ensure it is used for our own XSetSelection call replacing the selection. In this same situation, it will make the X server deem the request too old, and let LO win. If the compositor-side XSetSelection event does not happen in result to a XFixes selection notify event, the current event time will be used, and META_CURRENT_TIME as a last resort.

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.
