Summary: Okular thrashing or displaying blank window trying to
render PDFs which are fine in Adobe Reader
Product: okular
Version: 0.11.2
Platform: Ubuntu Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: PDF backend
AssignedTo: okular-devel@kde.org
ReportedBy: m...@pobox.com
Version: 0.11.2 (using KDE 4.5.5)
OS: Linux
I've encountered a PDF which renders really slowly in Okular, but is fine in
Adobe Reader.
http://carto.metro.free.fr/documents/CartoMetroLondon.v2.0.pdf
Reproducible: Always
Steps to Reproduce:
1. Download http://carto.metro.free.fr/documents/CartoMetroLondon.v2.0.pdf
2. Load it into Okular.
3. Hit 'zoom in' a couple of times.
4. Wait... and wait... and wait...
Actual Results:
Takes about 6 seconds to render when zoomed out to 50%. 18 seconds at 100%. At
200% it appears to give up and render a blank window, and top shows no CPU
activity.
Expected Results:
In Adobe Reader, the PDF renders in under 2 seconds at any zoom level.
I've seen similar problems in PDFs generated using LuaTeX, but wasn't able to
provide a good sample to file a bug report because they contained information
internal to my employer.
Computer is a Core i7.
