A particular window may be selected using the new xid (X-Window XID, eg a pointer) and xname (window title) properties. If both are specified, the XID is used in preference, falling back to xname if not found. Default (if none of xid and xname are specified, or if no such window is found) is to capture the root window. https://bugzilla.gnome.org/show_bug.cgi?id=546932
