Description raymondwagenmaker 2012-07-29 10:36:55 UTC

Slides created with a LaTeX beamer theme used by (part of) the CS department of Utrecht University fail to render correctly with poppler-0.20.x. The first page shows the background colors, subsequent pages are just gray. Text is invisible unless selected. I can neither see nor click the beamer navigation elements (or other images).

Example pdfs: all slides (except the last, since it's .ppt) available on http://www.cs.uu.nl/wiki/bin/view/Apa/CourseSchedule

Tested using evince/zathura. When run from a terminal, the error "Internal Error: cairo context error: invalid matrix (not invertible)" shows up repeatedly. Downgrading poppler and poppler-glib to 0.18.4 (all with Arch Linux packages) 'fixes' it. As far as I can tell, I have had cairo-1.12.2 since I first noticed this issue (but also with the working poppler-0.18.x).

(same problem with daily image of Ubuntu 12.10 amd64, which should also be 0.20.x)

Sorry, saying it belongs to cairo-backend is probably wrong, I'll leave further classification to more knowledgable people.

Works fine in the splash backend (i.e. Okular) moving it back to the cairo backend

Same issue here on Fedora 17 with poppler 0.18.4-3.fc17 and evince 3.4.0-2.fc17.
