I don't see that (but other minor redrawing errors).  I suspect your 
version of fontconfig and/or Xrender is different from mine.  I'll test 
this further on older X versions when Emacs has been released.  You can 
try to modify xterm.c here:

#ifdef HAVE_XFT
     if (! (s->for_overlaps_p
            || (s->background_filled_p && s->hl != DRAW_CURSOR)))
       XftDrawRect (s->face->xft_draw,
                    s->hl == DRAW_CURSOR ? &s->face->xft_fg : 
&s->face->xft_bg,
                    s->x,
                    s->y,
                    s->width + s->right_overhang,
                    s->height);

Remove the if-statement so the XftDrawRect is always done.  That should 
improve things, but also slow drawing down somewhat.

Thanks for pointing this out,
