I believe there is a bug here. I'm not sure if it is related to the performance issues, but when org-src-fontify-natively is t, new overlays keep getting added to the source block with each keypress in the source block. For instance, just typing this line of perl... #+begin_src perl my @apples = ("golden delicious", "braeburn"); #+end_src ...resulted in 54 identical overlays being added to the buffer. ,----[ M-x describe-text-properties | There are 54 overlays here: | From 39 to 88 | face org-block-background | From 39 to 88 | face org-block-background | From 39 to 88 | face org-block-background | From 39 to 88 | face org-block-background | ....[and so on] `---- The number keeps growing with more typing, since make-overlay is called without a test to see if an overlay already exists.
