If we end up trying to do a mode set on a DRM state that has already changed behind our back without us yet having seen the hotplug event we may fail with `EINVAL`. Since the renderer layer doesn't handle mode set failure, it'll still try to page flip later on, which will then also fail. When failing, it'll try to look up the cached mode set in order to retry the mode set later on, as is needed to handle other error conditions. However, if the mode set prior to the page flip failed, we won't cache the mode set, and the page flip error handling code will get confused. Instead of asserting that a page flip always has a valid cached mode set ready to look up, handle it being missing more gracefully by failing to mode set. It is expected that things will correct themself as there should be a hotplug event waiting around the the corner, to reconfigure the monitor configuration setting new modes.

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.
