Another thought: I've observed that in Org buffers -- but I almost exclusively work in such buffers, nowadays -- with "literate programming" aspects (I mean: with code blocks inserted in the flow of the text). And, something that's not on by default about those blocks is: --8<---------------cut here---------------start------------->8--- ;; fontify code in code blocks (setq org-src-fontify-natively t) --8<---------------cut here---------------end--------------->8--- Please add that as well in your test config, it could count! Thinking more about it, I'm not sure (anymore) I've ever seen the display problem in pure Emacs Lisp buffers, for example -- though, this may prove wrong (assumption to be taken with lots of caution). >> I *will* work with all these settings commented for the following hours and >> days, just to see whether the problem appears or not > > Thanks, that will help. I hope we'll catch it! Best regards, Fabrice
