I am sending this report at the request of org's built in monitor. org mode recovered gracefully and did not inconvenience me. I have attached my configuration state report. I was able to reproduce the bug twice by repeating the steps I outline below, but when I went to capture a backtrace I ran org-reload as instructed in the manual and that appears to have fixed the problem. I was working on some job applications in a org-file of ~1000 lines, ~30k characters. I keep all my org files relatively small, but I have thousands. I had org-columns activated and was editing a plain bulleted list under a subheading. I went to kill and yank a region of indented paragraph from above the list to beneath the list. I was met with a brief graphical stutter and the lines were visibly yanked back to the buffer in rapid sequence. Simultaneously the warnings buffer opened and I was solicited to send this message (multiple times, I think once per line). The text was ultimately pasted into position as I expect and my session did not suffer. I am sending this mail via my notmuch emacs mua. ------------------------------------------------------------------------ Emacs : GNU Emacs 31.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.43, cairo version 1.18.0) of 2024-08-29 Package: Org mode version 9.7.10 (release_9.7.10 @ /usr/share/emacs/31.0.50/lisp/org/)
