I retested this on a theory (see 164233.tar.gz). Test1.pdf is from the steps above, and produces a chunky result as described. test2.pdf however was created using the print to file method of creating pdf files, which I believe is a completely different library, and it looks right (at least on this system).
This leads me to believe that the issue is in /usr/lib/libreoffice/program/libpdffilterlo.so or OpenOffice/LibreOffice. ** Attachment added: "164233.tar.gz" https://bugs.launchpad.net/ubuntu/+source/evince/+bug/164233/+attachment/2901065/+files/164233.tar.gz ** Also affects: libreoffice (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/164233 Title: [Upstream] [hardy] Opening pdf with smooth gradient in Evince displays striped To manage notifications about this bug go to: https://bugs.launchpad.net/evince/+bug/164233/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
