 When opening TigerVNC the windows have no text and are completely blank.

 I'm fairly confident I have run into the issue described
 [https://github.com/TigerVNC/tigervnc/issues/767 here on GitHub]. This
 seems to suggest the problem is specific to machines running Mojave,
 although I am unable to confirm that.

 As described in that issue, the problem may actually lie with FLTK rather
 than being a problem with TigerVNC directly - see the
 [https://www.fltk.org/str.php?L3496 FLTK bug report].

 As an aside, I have installed and tested the official (and latest)
 TigerVNC 1.9.0 release and this works OK. Clearly though, I would prefer
 to have TigerVNC installed and managed by MacPorts instead.
