I can confirm this also happens on Arch Linux with latest updates (and emacs 29.x)

I’ve been using PlantUML for documenting almost everything. ORG, org-babel and PlantUML is indeed a lovely combo!

For a recent blog post I wrote this ORG file: https://github.com/dorneanu/roam/blob/main/org/blog/2023-07-17-documentation_as_code_for_cloud_plantuml.org

​

There I not only use org-babel to write PUML code but I also use things like `org-sbe` to

- *tangle* PUML files in a specific directory

- *generate* PNG files in another one

Make sure to view the RAW file.
