Since upgrading from Fedora 27 to Fedora 28, Emacs 26.1-3.fc28.x86_64, links and other fontified text in Org files appear as the underlying plain text. A few of them look correct, and deleting a marker character (e.g. square bracket) and reinserting it makes the link appear correctly for a while. The Messages buffer is full of things like this:
Error during redisplay: (jit-lock-function 501) signaled (wrong-type-argument listp org-level-4) Error during redisplay: (jit-lock-function 1001) signaled (wrong-type-argument listp org-level-4) Error during redisplay: (jit-lock-function 1501) signaled (wrong-type-argument listp org-level-3) Error during redisplay: (jit-lock-function 2001) signaled (wrong-type-argument listp org-level-3) Error during redisplay: (jit-lock-function 1152403) signaled (wrong-type-argument listp org-level-2) I've attempted to set jit-lock-mode to nil in .emacs, with no success. This Emacs has a built-in version of Org, 9.1.14, and I've tried 20181125 installed through Melpa. Nothing makes a difference. Any ideas? Peter.
