gtk3-nocsd is a small module that disables Gtk+ 3 client side decorations.

Since Gtk+ 3.10, many GNOME applications have begun using client-side header bars, which combine traditional window manager-provided title bars with client-side menu and tool bars. When used with gnome-shell, header bar applications use less screen space for window controls, and can directly update their own controls. The GNOME project has made project-wide adoption of header bars an official goal.
