As of ea483af9 we're calling this unconditionally from the GLX code so
the synthetic visual is in a lower select group. If Composite has been
disabled then GetCompScreen() will return NULL, and this would crash.
Rather than force the caller to check first, just always return FALSE if
Composite is disabled (which is correct, since none of the visuals will
be synthetic in that case).

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
