That explanation makes sense. Thanks! In fact, KDE-4.2 has a much better reputation than KDE-4.1 so these color/text position rendering issues for -dev svg results (as well as other SVG results) may already be resolved by KDE-4.2. In any case, I now feel we shouldn't worry too much about svgqt until the fundamental validation issues get straightened out for the SVG files produced by Qt4 so I now have disabled svgqt by default. The remaining big concern for me is still the size issues for all the other qt-related devices. * Would you be willing to go through the same xdpyinfo and GUI measuring exercises (with an actual meter stick) I asked Alban to do to make sure we all have dimensions and resolutions configured right on our various Linux systems, X configurations, and monitors? * For -dev pngqt do you get the ~20 per cent smaller glyphs I do or the normal-sized glyphs like Alban does? * For -dev qtwidget do you get the half-size glyphs I do or the normal-sized glyphs like Alban does? (For the last two questions please refer back to the screenshots we both recently sent to the list.) Thanks in advance for your help with these qt glyph size questions. It will be a big help to know what the situation is for each of the Linux platforms you have access to. Alan __________________________ Alan W.
