When using DesktopIcons extension and clicking in an icon, gnome-shell starts an infinite loop caused by the first focus change that may trigger on X11 a focus in/out event that leads to stage activation/deactivation which never ends. This happens because as part of meta_x11_display_set_input_focus_xwindow() to focus the X11 stage window, we unset the display focus, but this also causes to request the X11 display to unset the focus since we convolute by calling meta_x11_display_set_input_focus() with no window, that leads to focusing the no_focus_window and then a focus-in / focus-out dance that the shell amplifies in order to give back the focus to the stage. In order to fix this, mimic what meta_display_set_input_focus() does, but without updating the X11 display, and so without implicitly calling meta_x11_display_set_input_focus(), stopping the said convolution and properly focusing the requested xwindow. Also ensure that we're not doing this when using an older timestamp, since this check isn't performed anymore.

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.
