Mutter (a contraction of "Metacity Clutter") is a window manager for the X Window System, and is in the process of becoming a Wayland compositor; it became the default window manager in GNOME 3, replacing Metacity.[4] While Metacity uses GTK+ for rendering, Mutter uses a graphics library called Clutter, and also supports OpenGL by Clutter.

The Mutter window manager can function as standalone window manager application for GNOME-like desktops, and serves as the primary window manager for the GNOME Shell desktop,[5] which is an integral part of GNOME 3. Mutter is extensible with plugins and supports numerous visual effects.

Performance[edit]

OpenGL games run with a performance hit when using a compositing window manager; in June 2010, Phoronix evaluated this as similar for Mutter[6] and Compiz.[7]
