This protocol is limited to Xwayland only and is not visible/usable by any other client. Mutter uses the following mechanisms to determine if an X11 client should be granted a grab: - is "xwayland-allow-grabs" set? - if set, is the client blacklisted? - otherwise, has the client set the X11 window property _XWAYLAND_MAY_GRAB_KEYBOARD on the window using a client message? - if not, is it a client white-listed either via the default system list or the settings "xwayland-grab-access-rules"? https://bugzilla.gnome.org/show_bug.cgi?id=783342
