Are you saying that you can reboot your computer, restart Emacs, open the relevant Org file, evaluate the source block (without any C-c ') and you still see the problem? If so, I wonder if it's a real but intermittent problem in your code that was somehow made more likely by the original workflow, and now you're just being unlucky? > > Does anyone have any idea what might be going on?
