Okular / Poppler very slow to render the 1st page of MagPi magazine issue 87
This magazine issue has a publicly available PDF that can be directly downloaded here.
For some reason, it seems the 1st page of that document is particularly heavy, compared to the 2nd page.
With Poppler 23.08.0 on Fedora 39 on Wayland, Evince 45 and Okular 23.08 take about 15-20+ seconds to render the first page at reasonable/normally sized window sizes.
Here is the output of Sysprof 46, showing what happens when opening and loading that document on the 1st page directly:
Okular 23.08 | Evince 45 |
---|---|
FWIW, PDF.js, while still slow, is able to render it about twice faster (corresponding issue here)
