 Replying to [comment:6 snorfalorpagus]:
 > Confirmed this is an issue with cairo, or at least GRASS' use of it. If
 I compile --without-cairo, it falls back on... I don't know what... but
 the legend/scalebar display OK.

 The default display driver is cairo if GRASS was built --with-cairo, and
 the PNG driver otherwise. You can force the use of a specific driver with
 e.g.:
 {{{
 export GRASS_RENDER_IMMEDIATE=PNG
 }}}

 The cairo driver uses cairo's text rendering and, where available,
 !FontConfig for font selection. If !FontConfig isn't available, the only
 non-stroke fonts which the cairo driver supports are "sans", "serif" and
 "mono" (plus bold and/or italic variants). Unlike the PNG driver, the
 cairo driver cannot use !FreeType directly (i.e. without going through
 !FontConfig).
