Hi all,

With the following sample code, I observe the results shown in the attached image.  The first two "ab" have a border, but the last one only has three-quarters of its border: the right side is missing.

(defface my-button
  '((t :box(:line-width -4 :style released-button)
       :background"lightgrey":foreground"black"))
  "Button face")

(with-current-buffer (get-buffer-create "button")
  (insert "\n")
  (insert (propertize "ab" 'face 'my-button))
  (insert " ")
  (insert (propertize (compose-chars ?a '(Br . Bl) ?b) 'face 'my-button))
  (insert " ")
  (insert (propertize "ab" 'display (compose-chars ?a '(Br . Bl) ?b) 'face 'my-button))
  (insert " ")
  (pop-to-buffer-same-window (current-buffer)))

Clément.
