Thanks!!!
Testing with the flatpak version was a good idea.
The flatpak version was almost instant for me.
I compared the settings under Settings -> Configure Okular -> Performance
The flatpak had "enable graphics antialias" checked.
My local okular had it unchecked. (I had done that a long time ago because I
thought that antialiasing made it slower.)
I checked it, and it went from a minute to almost instant rending the sample
PDF.
I had thought that antialias rendered at a higher resolution and then averaged
the high resolution image down to the displayed resolution, so enabling
antialias is usually a few times slower.
I didn't expect that enabling antialias in okular would be about 50 times
faster instead of a few times slower.
If antialias is off, does okular revert to a slower method (like using poppler
splash)?
I tried unsetting antialias for both text and graphics to see if having them
set differently was the problem, but having them both unchecked was still slow.
Anyway, thanks, enabling graphics antialias solved the problem!
Thanks again!
William
