Version: (using KDE 4.1.3) OS: Linux Installed from: Fedora RPMs I had 'Use KDE themes for non-KDE apps', "Install scrollbar fix" for firefox, etc., but the result is ugly. I want to revert back to the gtk styles. But I don't find any option for that. "Appearance->GTK Style and Fonts" only asks "Use my KDE4 style" or "Use another style", which is another KDE style. There's no way I can remove the KDE effects from GTK apps (just firefox; I don't know about others). Also, till these options make it to some release, please let me know how I can revert the "install scrollbar fix" as well as the KDE theming.
Those options are related to "gtk-qt-engine" that is not an official KDE part. You can ask it to the developer at : http://gtk-qt.ecs.soton.ac.uk/
