Description jorgemartinezvegara 2025-03-04 10:58:05 UTC

Clicking on an index entry in "Facing pages" view mode scrolls to the wrong page.

STEPS TO REPRODUCE

1. Open a PDF file in Okular.
2. Set the view mode to "Facing pages" (View → View Mode → Facing pages).
3. Click on an entry in the index to navigate to a specific section.

OBSERVED RESULT
Okular jumps to the wrong page instead of the one linked in the index.

EXPECTED RESULT
Okular should navigate to the correct page when clicking an entry in the index, as it does in "Single page" mode.

I'm not sure if it's strictly a duplicate, but https://bugs.kde.org/show_bug.cgi?id=452430 seems at least probably related?
