Diagram thumbnail does not correspond to actual diagram

[kostasadriano]

Describe the bug: Diagram thumbnail does not correspond to actual diagram.

Expected behaviour: Thumbnail should correspond to the contents of the diagram.

Environment:

• Version: 2.4.0
• Platform: Tested with Desktop App
• OS: Tested on Windows The behavior is probably the same for other versions.

To Reproduce: Open Threat Dragon. Open a model. The diagram thumbnail is a generic one.

Any additional context, screenshots, etc:

Agreed @kostasadriano , and it would be good if it was an actual thumbnail rather than a generic diagram The Plot4ai diagrams have the Plot4ai logo, and perhaps it would be good to have a 'STRIDE' logo instead - if there is one?

Possible Solutions for Incorrect Diagram Thumbnail 1️⃣ Ensure Thumbnail Updates – Trigger thumbnail regeneration after changes. 2️⃣ Check Rendering Logic – Verify that the correct diagram is captured and saved. 3️⃣ Fix Caching Issues – Clear old thumbnails to prevent outdated previews. 4️⃣ Enable Manual Refresh – Add an option to regenerate thumbnails on demand. 5️⃣ Check File Save Process – Ensure the latest diagram is properly stored before generating the thumbnail.
