zathura-pdf-mupdf (zathura support for mupdf backend) The zathura-pdf-mupdf plugin adds PDF support to zathura by using the mupdf rendering library (replacing the poppler-based PDF support from the zathura package). To switch between the mupdf and poppler backends without reinstalling packages, adjust the symlink at /usr/lib(64)/zathura/libpdf.so. It should point to either pdf/libpdf-mupdf.so or pdf/libpdf-poppler.so. You can also reinstall zathura to switch to the poppler backend, or reinstall zathura-pdf-mupdf to switch to the mupdf backend (whichever was installed last "wins").
