Nasty and hard to diagnose bug. So, what is the problem? On Qt platform such as KDE ChGtk has got problem to choose proper EditField frame. This bug may manifest as a complete lack of frame (Look: oxygen-gtk theme).

Following code should stabilize drawing EditField frame on Qt platform(KDE):

    int efm = 0;
    {
        EditField::Style& s = EditField::StyleDefault().Write();
        Image img;
        for(int i = 0; i < 4; i++) {
            GtkWidget *w = Setup(gtk_entry_new());
            if(i == CTRL_PRESSED)
                GTK_WIDGET_FLAGS (w) |= GTK_HAS_FOCUS;
            if(i == CTRL_DISABLED)
                GTK_WIDGET_FLAGS (w) &= GTK_SENSITIVE;
            img = GetGTK(w, GTK_STATE_NORMAL, GTK_SHADOW_IN, "entry", GTK_SHADOW, 20, 20);
            if(i == 0)
                efm = max(ImageMargin(img, 4, 0), 1);
            if(!Qt) 
                img = GetGTK(w, GTK_STATE_NORMAL, GTK_SHADOW_IN,
                        "entry", GTK_SHADOW, 2 * efm + 3, 2 * efm + 3); // <- It seems that this line causing problems on Qt for some resons!!!
            ImageBuffer eb(img);
            eb.SetHotSpot(Point(efm, efm));
            s.edge[i] = Image(eb);
            s.activeedge = true;
            gtk_widget_destroy(w);
        }
    }

Above code was tested on Ubuntu(Gtk - Nothing has changed) and Kubuntu(KDE). On KDE I had tested on multiple themes.

P.S.
This patch includes all my previous patches to ChGtk.cpp.
