Gtk-qt-engine 0.7 does not solve all GTK drawing problems in GRAMPS. Eg issue {{bug|786 }} '''is not resolvedin 2006'''. Should other problems come up which you think are due to gtk-qt-engine, contact the developers. You can test this by switching in System Settings->Appearance->GTK Styles and Fonts, to style Rayleigh. It doesn't look nice on KDE, but should prove if a problem is engine related, or just a bug in GRAMPS.
