I'm using OpenSuSE 11.1. I've seen the same problem ocurring on Kubuntu. This bug report might be related: https://bugs.launchpad.net/ubuntu/+source/kdegraphics/+bug/48146 This has been fixed since quite a while (poppler version 0.12 definitely works). Hi, thank you for updating the status! I think this issue is related with the poppler's default setting of hinter for FreeType2. It was disabled by default since 2009-Oct-6. I made a comparison of the font rasterization results by latest FreeType2 with hinter enabled/disabled: https://www.codeblog.org/blog/mpsuzuki/images/20100904_0.png You can find the dropout issue can occur by the latest FreeType2 when hinter is enabled. When you find similar problem in other application, please remind this. |

Created attachment 24576 [details] PDF file with bad rendering Okular has a problem with certain PDF files generated by pdfLaTeX. The characters appear too thin and are difficult to read. Attachments include a PDF file triggering this problem and the corresponding LaTeX source file. I also attached screenshots from Acrobat Reader and xpdf which render the file correctly for comparison. Please note, that the rendering looks fine if there are no T1 encoded fonts used (However T1 fonts are required to properly typeset German texts with umlauts).
