An override redirect window is not under the control of the window manager.
This means it won’t have a titlebar, won’t be minimizable, etc. - it will
be entirely under the control of the application. The window manager
can’t see the override redirect window at all.
Override redirect should only be used for short-lived temporary
windows, such as popup menus. gtk.Menu uses an override redirect
window in its implementation, for example.
