this report has been filed here: https://bugs.edge.launchpad.net/ubuntu/+source/poppler/+bug/296063 "Open attached PDF file. The embedded charts are rendered with a red halo effect that should not be there. When opened in Adobe Reader (v6,7,8), the charts are rendered correctly (without red halo). These PDF files are generated using JasperReports, the iText PDF rendering library, and JFreeChart graphics library. They work and appear normally in all versions of Adobe Reader." http://launchpadlibrarian.net/19520634/red-halo.pdf screenshot showing the issue: http://launchpadlibrarian.net/19523167/redhalo.png
