(set-face-attribute 'mode-line nil :box '(:line-width 15))

;; Notice the obscured coding system flag in the mode-line. Mouse
;; over the mode-line and observe the mode-line status flags become
;; visually corrupted.

;; Further, turn off the mode-line's 3D effects by setting :box 
;; atttributes.

(set-face-attribute 'mode-line nil :box nil)

(set-face-attribute 'mode-line-highlight nil :box nil)

;; Mouse over the mode-line and observe the unexpected
;; mode-line-highlight face.

;; Note that this is reproducible in 24.4.
