--- Comment #4 from Kevin Kofler kevin@tigcc.ticalc.org --- The -11 screenshot is using subpixel antialiasing, the -13 one grayscale. There are also some other hinting differences, the characters don't end up at the same positions. Are you sure both of those screenshots are from Fedora freetype packages, no freetype-freeworld, freetype-infinality or the like?
