Description RSB 2012-08-05 12:23:54 UTC

On some pages Okular needs very long to present the next page while CPU is at 100%. Sometimes you have to wait 30s until the next page is shown. I'll add a exemple pdf to this report for trying.
This is especial annoying in prensentation mode.

Reproducible: Always

Steps to Reproduce:
1. open attached example pdf
2. go to presentation mode
3. try to switch through the pages
Actual Results:  
pages need very long to load. CPU is at 100% while loading.

Expected Results:  
faster loading.

System:
openSUSE 12.1
KDE 4.9

Thank you for reporting this bug, but we in Okular are not responsible for the rendering speed of pdf files, as you have correctly identified the poppler library is the one doing the rendering so there is not much we can do in Okular to speed it up.

Please report a but in the poppler bug tracker at https://bugs.freedesktop.org

Thanks for caring about Okular :-)
