It's the single word "California" rendered in Liberation Serif at 12pt, 120% zoom on my screen. In this case, among many other issues, the renderer has chosen to place the 'r' and 'n' characters so close together that they actually overlap and appear to be an 'm'. It's a good illustration of how the lack of subpixel positioning for glyphs ruins any attempt at proper kerning. Incidentally, the related bug is about the fact that disabling pair kerning ameliorates some of these problems. In this case, an extra pixel is placed between the 'r' and 'n', probably because kerning nudges them slightly closer together and creates situations where rounding will force them to overlap. This specific image was created with a script I wrote to rerender a screenshot as virtual subpixels with the same RGB alignment as my actual screen, and then point upscaled three times. This allows users who may be on very different screens to see exactly what rendering decisions Libreoffice + Fontconfig is making for my screen. -- You are receiving this mail because: You are the assignee for the bug.
