Whitespace-mode not compatible with Auto-complete

[gfreezy]

While I enabled whitespace-mode, some lines of the popup layer of auto-complete is covered by something.

auto-complete mode is known to cause all sorts of graphics corruption. That's why I've dropped it from Prelude. I'll have a look at that particular problem when I have some spare time.

I have a workaround if anyone is interested:

(set-default 'my-prev-whitespace-mode nil)

(defadvice popup-draw (before my-turn-off-whitespace)
  "Turn off whitespace mode before showing autocomplete box"
  (make-local-variable 'my-prev-whitespace-mode)
  (if whitespace-mode
      (progn
        (setq my-prev-whitespace-mode t)
        (prelude-turn-off-whitespace))
    (setq my-prev-whitespace-mode nil)))

(defadvice popup-delete (after my-restore-whitespace)
  "Restore previous whitespace mode when deleting autocomplete box"
  (make-local-variable 'my-prev-whitespace-mode)
  (if my-prev-whitespace-mode
      (prelude-turn-on-whitespace)))

(ad-activate 'popup-draw)
(ad-activate 'popup-delete)

in latest prelude version prelude-turn-off-whitespace function has been removed, code fixed bellow:

;;; advice for whitespace-mode conflict
(defvar my-prev-whitespace-mode nil)
(make-variable-buffer-local 'my-prev-whitespace-mode)

(defadvice popup-draw (before my-turn-off-whitespace)
  "Turn off whitespace mode before showing autocomplete box"
  (make-local-variable 'my-prev-whitespace-mode)
  (if whitespace-mode
      (progn
        (setq my-prev-whitespace-mode t)
        (whitespace-mode -1))
    (setq my-prev-whitespace-mode nil)))

(defadvice popup-delete (after my-restore-whitespace)
  "Restore previous whitespace mode when deleting autocomplete box"
  (if my-prev-whitespace-mode
      (whitespace-mode 1)))

(ad-activate 'popup-draw)
(ad-activate 'popup-delete)

Someone should really fix autocomplete-mode upstream. It's not right to expect users to have to apply workarounds like this one.
