Good to hear, but as some were finger pointing the overlays, and as I added one for every block... But, OK, better like that! For the sake of completeness, know that I first tried to add the background fontification as a text property, but that made the other properties disappear (annihilating the native fontification in fact). No a solution, or I did not try the right way -- which is entirely possible, seen my poor knowledge on this subject (I have to admit I succeeded by trials and errors). > So, I turned off =org-src-fontify-natively= and things are back to > normal: next-line is as fast as previous-line.
