When using Okular as previewer in PDFTex workflow, preparing beamer slides, the following usability hell occurred:

• LaTex/Beamer slides should be compiled to PDF with metadata "StartFullScreen"
• But while editing, on every PDF change/and reload, the user gets a modal popup "The document requested to be launched in presentation mode." "Do you want to allow it?"

(See part.cpp)

• This makes typical Slide/LaTeX/Beamer editing workflow completely unusable.

FIX:

• Completely disable this warning on reload of the changed document.

1. Download and unzip test materials

First Test:

1. Run demo.sh
2. Open generated demo.pdf in Okular
3. Click 'Deny Request' on full-screen prompt
4. Reload pdf by pressing F5 or File>Reload
5. demo.pdf should reload without full-screen prompt showing again

Second Test:

1. Run demo.sh
2. Open generated demo.pdf in Okular
3. Click 'Deny Request' on full-screen prompt
4. Keep demo.pdf open in Okular and run demo.sh again
5. demo.pdf should automatically reload without full-screen prompt showing again
