SUMMARY
When I view certain pdfs with okular using the trim margin and facing pages feature, some regions of the pdf don't render and just appear white. See attached screenshot of this pdf:
https://docs.kde.org/trunk5/en/applications/fundamentals/fundamentals.pdf
This seems to only occur when the okular window is at least ~3000 pixels wide; eg, a fullscreen okular window has this issue on my 4k screen.

STEPS TO REPRODUCE
1. Open https://docs.kde.org/trunk5/en/applications/fundamentals/fundamentals.pdf
2. Make okular window at least ~3000 pixels wide.
3. Enable trim margin
4. Use facing pages

OBSERVED RESULT
Large unrendered region, as seen in screenshot.

EXPECTED RESULT
Everything should be rendered.
