Itʼs ns_dumpglyphs_stretch, which is doing exactly as itʼs told:
drawing the background to the right edge of the frame. Thatʼs because
in xdisp.c:display_line we have:
/* Make sure that a non-default face is extended
up to the right margin of the window. */
extend_face_to_end_of_line (it);
which later causes set_glyph_string_background_width to set the
background_width of the glyph to the full width (commenting out that
call makes NS work the same as X11 for this specific case).
What I donʼt understand is that under X11 Emacs takes exactly the same
code path, yet somehow it doesnʼt end up setting the background up to
the right edge.
