Thanks for letting me know and for taking the time to identify the cause of the PDF export issue. That information is very helpful. I’ll investigate why external images can cause the export to fail.
Regarding the Mermaid diagram, the syntax in your screenshot looks valid, so the rendering failure may be related to the WebKit backend on Garuda Linux. Could you please run GDDKit from the terminal, try rendering the diagram again, and share any output or error messages you see?
It would also be helpful if you could share the output of:
pacman -Q | grep -E 'webkit|wpe|gtk'
This should help me identify the cause of the rendering failure.
This is it:

Thanks, this is very helpful! WebKitGTK 4.1 and GTK3 are both installed, so a missing dependency doesn’t seem to be the cause.
I haven’t identified the exact cause yet, but I’ll investigate it using the diagram and package versions you provided. The application currently catches Mermaid rendering errors and shows the source as a fallback, which is why nothing appeared in the terminal.
Thanks again for taking the time to provide all this information!
If you need it for your tests, I could provide you with a zip file with my GDD. Just tell me if you need it and I'll find the way to send it to you :)
Thanks for the offer! I don’t need the GDD file just yet. I’ll first try to reproduce the issue on Garuda Linux and let you know if I need it.
