   I reproduced this on a local Superset setup.
   
   - Dashboard PDF export does work
   - A PDF file is successfully generated and downloaded
   - deck.gl charts are included in the exported PDF as static rasterized images
   - CSV and image exports at the chart level also work correctly
   
   This behavior appears to be expected, as dashboard PDF export relies on a 
headless browser screenshot, and deck.gl (WebGL) layers are rendered as images 
during this process.
   
   I’ve attached a short screen recording showing:
   
   - Creating a dashboard with a deck.gl chart
   - Exporting the dashboard to PDF
   - Successfully opening the generated PDF
   
   Based on this, this does not seem to be a functional bug but rather a known 
limitation of WebGL-based visualizations during PDF export.
