Version: (using KDE 4.2.0) Installed from: SuSE RPMs Wish/bug? The problem is related to all pdf generated with latex. Consider letter U, in kpdf I see vertical lines like | | when I zoom in I see || || they are thicker. In Okular it is different, it is always something like this: || | one thick, one thin. Also the are other effects, like in small zoom, I see text quite clearly, I zoom in, and the quality is worse -- some lines (of the font) are super thick -- like horizontal dash in "e". Only in huge zoom Okular quality is on par with kpdf.
Okular, unlike KPDF, does not render documents on its own anymore, but uses the Poppler library. Please report the problem to the Poppler bug tracking system, https://bugs.freedesktop.org, "poppler" product. Don't forget to attach a document showing the issue, and to provide the info about the version of your poppler library.
Pino, thanks. See: https://bugs.freedesktop.org/show_bug.cgi?id=20143
