I've now reproduced after setting
(setq jit-lock-antiblink-grace nil)
Which turns off the antiblink feature _almost_ entirely. I've also been
able to reproduce it from the command line via:
~/Source/Emacs/emacs-27/src/emacs -Q ~/tmp/taks-file.latex
\
--eval "(progn
\
(require 'org)
\
(require 'org-table)
\
(orgtbl-mode)
\
(remove-hook 'post-command-hook
\
'jit-lock--antiblink-post-command t))"
Which _completely_ turns off the antiblink feature.
It doesn't need a window system, -nw is fine to reproduce.
This was with a fresh build of the Emacs 27.1 tag.
It's hard to reproduce sometimes, but iterating the undo/paste rectangle
cycle eventually gets one there. It has to be done on the very same
file that Tak Kunihiro posted. Sometimes I mess the file slightly (in
ways that I can't tell) and it doesn't happen again.
Tak Kunihiro, what is in your opinion the deciding character of these
files? I.e. what did you change from the first file (where I couldn't
reproduce) to the second?
I'm quite lost as to why this happens, of course, but it seems it's
always coming from syntax-ppss. When I evaluate that definition (rather
than compiling), I get more clues:
Debugger entered--Lisp error: (error "Marker does not point anywhere")
>(#<marker in no buffer> 2919)
(and old-pos (> old-pos pos))
(if (and old-pos (> old-pos pos)) (setq old-pos nil))
(let* ((cell (syntax-ppss--data)) (ppss-last (car cell)) (ppss-cache (cdr
cell)) (old-ppss (cdr ppss-last)) (old-pos (car pps$
(progn (set-syntax-table (or syntax-ppss-table (syntax-table))) (let* ((cell
(syntax-ppss--data)) (ppss-last (car cell)) (pps$
(unwind-protect (progn (set-syntax-table (or syntax-ppss-table
(syntax-table))) (let* ((cell (syntax-ppss--data)) (ppss-last $
(let ((table (syntax-table)) (buffer (current-buffer))) (unwind-protect
(progn (set-syntax-table (or syntax-ppss-table (synta$
syntax-ppss()
I'll keep looking a bit, but at this point it doesn't seem to have
anything to do with the antiblink feature. I might be wrong, but I
think that only shows up first in the messages buffer because it's
unlucky enough to be one of the first users of syntax-ppss after a
command.
