Test2.pdf is a postscript file, not pdf. So it will be rendered by ghostscript when viewed with evince.
The problem is caused by libreoffice. The "gradient" is actually a series of shaded rectangles. In fact the rectangles are not even correctly aligned. There is a tiny gap between each one. Cairo (used by evince) has a problem with showing lines between adjacent fills due to antialiasing. There is no easy way to fix this. And the small gaps between the rectangles caused by libreoffice will make the problem worse. The best solution is for libreoffice to use PDF gradients to draw the shading. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/164233 Title: [Upstream] [hardy] Opening pdf with smooth gradient in Evince displays striped Status in Evince document viewer: New Status in Poppler: New Status in “evince” package in Ubuntu: Triaged Bug description: 1) lsb_release -rd Description: Ubuntu 11.04 Release: 11.04 2) apt-cache policy evince evince: Installed: 2.32.0-0ubuntu12.2 Candidate: 2.32.0-0ubuntu12.2 Version table: *** 2.32.0-0ubuntu12.2 0 500 http://us.archive.ubuntu.com/ubuntu/ natty-updates/main i386 Packages 100 /var/lib/dpkg/status 2.32.0-0ubuntu12 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/main i386 Packages 3) What is expected in Impress via the Terminal: cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/164233/+attachment/2281555/+files/example.odp && loimpress -nologo example.odp export the file with Gradient 1 inserted into the background to pdf ( https://bugs.launchpad.net/ubuntu/+source/evince/+bug/164233/+attachment/2281556/+files/example.pdf ), open the pdf with Evince and it looks as it does in both Impress and Adobe Reader. 4) What happens instead is Evince shows a striped gradient.
