That is not the place I was talking about. That is the gnome-settings-daemon default, it only applies when you're running gnome-settings-daemon as your XSettings manager (i.e., basically only under GNOME). I'm talking about the toolkit default inside GTK+ 3, which is used if the XSetting is NOT set. That is what recently changed. xsettings-kde, the XSettings manager running in KDE Plasma sessions, expects the toolkit to honor the hardware DPI if the relevant XSetting is not set, as Qt does. It only sets an explicit DPI value if the user set an explicit DPI value in KDE System Settings. So GTK+ 3 now displays with the wrong font sizes in KDE Plasma sessions.
