'face '(:foreground "red" :weight bold) * Second overlay . . . 'face '(:underline "yellow" :weight normal) [The same result also happens if the bolded foreground face is a glpyh in the `buffer-display-table`, and where only one (1) overlay contains a *normal* weight underline. So, this issue does not appear to be exclusive to only the presence of overlapping overlays.] The desired result is a bold foreground for the text, and a normal weight underline. That result can be achieved if the cursor does not touch the overlapping overlays. Once the cursor has touched the overlapping overlays, however, the underline takes on a *bold* visual attribute. This improper *bold* attribute may extend for the entire length of the overlay, depending upon which direction the cursor is moving and other overlays that may be present. I was not able to correct this situation by setting priorities. In my various tests, setting priorities only served to choose one overlay over the other -- i.e., setting priorities do not permit the overlays to co-exist in harmony. The thread that I opened on Stackoverflow contains some screen shots and a recipe to reproduce the error. It is not necessary to use flyspell or hl-line-mode to reproduce the error, that was simply the example I chose because it is the one where I always see the error. Perhaps the reason why the initial test by @Drew may not have yielded the same result is that his cursor was not touching "mal-normal" -- had his cursor touched that section of the buffer, the same result as I experienced may have occurred. I also use OSX, but it may not be an OS specific issue. http://stackoverflow.com/questions/24313953/overlays-how-to-prevent-bold-faces-from-trumping-non-bold-faces Here is the recipe -- just adjust the path to the `ispell-program-name`: ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; GNU Emacs 24.4.50.1 (x86_64-apple-darwin10.8.0, ;; NS appkit-1038.36 Version 10.6.8 (Build 10K549)) of 2014-06-01 on MP.local (set-face-attribute 'default nil :background "black" :foreground "white" :font "Courier" :height 180) (tool-bar-mode -1) (require 'ispell) (require 'flyspell) (setq-default ispell-program-name "/Users/HOME/.0.data/.0.emacs/elpa/bin/aspell") (custom-set-faces '(flyspell-incorrect ((t (:foreground "yellow" :weight bold )))) '(highlight ((t (:underline "red" :weight normal))))) (defun zoom () (interactive) (setq buffer-face-mode-face `(:height 575)) (buffer-face-mode 1)) (defun test-number-one () (interactive) (switch-to-buffer (get-buffer-create "test-number-ONE")) (zoom) (turn-on-flyspell) (setq flyspell-mark-duplications-flag nil) (setq flyspell-duplicate-distance 0) (hl-line-mode 1) (insert "This is `test-number-one`."
