Hi, With the current org-do-latex-and-related function, fontification of a region before a LaTeX fragment repeatedly adds the 'org-latex-and-related face to the fragment.
You can reproduce with an org buffer with the following content. #+BEGIN_SRC org Foo $a^2 + b^2 = c^2$ #+END_SRC - Use (setq org-highlight-latex-and-related '(latex)) - Write some text at the end of the first line, triggering refonfication of the line - For each character inserted, the org-latex-and-related face is added (as a duplicate) to the fragment, as you can check using describe-text-properties. The attached patch fixes this. -- Sébastien Miquel
