Hi António; Thanks for the above information. In general I would advise adopting -DENABLE_DYNDRIVERS=ON (or dropping -DENABLE_DYNDRIVERS=OFF since ON is the default) since that build is much less tricky than the -DENABLE_DYNDRIVERS=OFF case. Also, if you want to do build tree tests like the test_all_qt target I suggest below, then you should also use the cmake option -DBUILD_TEST=ON. SuSe has a long historical record of distribution expertise concerning KDE and Qt. So perhaps they (or the upstream Qt developers) have already fixed in Qt5.3.1 the character offset issue I empirically corrected for the Qt-5.2.1 case. What happens in the pdf case when you remove that PLplot "correction"? (Look for empirical_yOffset in bindings/qt_gui/plqt.cpp in the source tree and set it to 0.) Note, to obtain complete tests of qt results, try the "test_all_qt" target, e.g., run make -j4 test_all_qt right after you run the cmake command (with -DBUILD_TEST=ON). You should expect interactive test results to flash momentarily on your screen as well as a large accumulation (something like 2GB!) of plot file results generated by all the qt devices collected in examples/test_examples_output_dir. Then to see what the results are like in a wholesale way you would want to do something like this cd examples/test_examples_output_dir for FILE in x*.pdfqt; do echo $FILE; display $FILE; done where display in the imagemagick command that allows you to view most file formats. And similarly for x*bmpqt and the rest of the qt file device results. Also, if you want to see the interactive results a lot slower (to allow you to carefully evaluate the rendering), then run examples/c/x00c -dev qtwidget etc., for all our standard examples after the above test_all_qt target is run (which should build all required dependencies for the suggested -dev qtwidget tests). If zeroing empirical_yOffset produces perfect pdf results (as compared, say, to the perfect cairo results for all our examples displayed on our website) for you, then how many other qt devices also produce exact rendering agreement with those pdf results and how many qt devices (as you have already shown for -dev pngqt) still have alignment or font issues? Note, we found lots of Qt4 rendering and font bugs with all but the later (i.e., x >= 5) versions of Qt4.x. So I expect it is similarly going to take several more "minor" releases of Qt5 before all the character alignment and font issues that affect the PLplot qt devices are fixed. So for now, our qt device users who want absolute reliability should probably stick with Qt4, but it would still be good if you are willing to do the testing requested above just to see where we stand with the rendering quality of Qt5. Note also that I want to be quite selective of what Qt5 versions I build since that is a long process, but if you report rendering perfection for at least one qt device (e.g., -dev pdfqt) for all our standard examples with the opensuse 5.3.1 version of Qt, than I would be willing to try to build the upstream 5.3.1 to see whether I get similar results for upstream or whether the rendering fixes relative to 5.2.1 are only in the opensuse version.
