Reporting this from emacs 28, but I first noticed in a freshly compiled version of emacs. This does NOT occur in org 9.5.5 that is included with emacs 28. I do not have any special configuration for org babel. Open emacs. Open some .org file with src blocks in some folder /some.org Notice a new folder called babel-stable-nnn (some randome 3 digit number) appears in the folder containing the .org file. I think these should be created in my /tmp/ folder, not the folder containing the .org file. Sometimes they ARE created in my /tmp/ folder. These bable-stabe-nnn folders are usually deleted but they sometimes persist even after closing emacs. The following generated by M-x org-submit-bug-report: My full org configuration follows that.
