No text at all, or small text. Do previous versions of FLTK work
properly?

You need to look up the XLFD font spec that's being sent
to "X11" for processing. This should be in the XLoadFont
code.

Fl_Box *box = new Fl_Box(20,40,300,100,"Hello, World!");
box->box(FL_UP_BOX);
box->labelfont(FL_BOLD+FL_ITALIC);
box->labelsize(36);
box->labeltype(FL_SHADOW_LABEL);
window->end();
That resulted in the following messages:
findfont_nowild: fail
findfont: FINI nowild fixed = (null) height 32
findfont: START 6x13 0,0
findfont_nowild: fail
findfont: FINI nowild 6x13 = (null) height 32
XLoadFont('fixed') = '(null)' height 32 [0]

This is likely that a fonts.alias or other file required to translate
the fonts specified in FLTK 1.3 and sent to NXLIB can
be found in NXLIB's font directories. This is complicated,
but you will need fonts.dir, fonts.alias, and possibly other
files that will allow truetype fonts to be selected, so that the
large size can be created. A workaround would be to build
an alias for a fixed-size 36 font, which would be found with
the variable sized XLFD font spec.
