(defface my-line
  '((((type graphic)) :inherit font-lock-comment-face :strike-through t)
    (((type tty)) :inherit font-lock-comment-face :underline t))
  "Line face")

(defun my-line-glitch-repro ()
  (interactive)
  (with-current-buffer (get-buffer-create "*foobar*")
    (insert "\n"
            (propertize " "
                        'face 'my-line
                        'display '(space :width 80))
            "\n")
    (goto-char (point-min)))
  (pop-to-buffer-same-window "*foobar*"))

Try M-x my-line-glitch-repro in both a textual and graphical session,
then put point on the space displayed as a 80 characters wide line.  In
the graphical instance the line will be hidden (with the beginning being
displayed *in* the cursor's rectangle in reverse video), in textual
instances it's still visible (assuming your terminal supports
underlining).
