xterm is restoring the cursor to the wrong row position with the 
ESC 8 restore cursor (DECRC) sequence.  It was subtracting the value of the
top margin from the row.  Here is a patch to fix that bug.

        screen->curgr = sc->curgr;
        term->flags &= ~(BOLD|INVERSE|UNDERLINE|ORIGIN);
        term->flags |= sc->flags & (BOLD|INVERSE|UNDERLINE|ORIGIN);
!       CursorSet(screen, sc->row - screen->top_marg, sc->col, term->flags);
  }
