I recently installed KDE (I was using GNOME). After that, I found for gnome applications, KDE font settings is applied even when I log in using GNOME. Whatever I do in appearance-fonts, all gnome applications follow the settings from KDE Personal Settings. (Application Appearance -> Fonts)

I lost all the subpixel hinting, and I finally just found out that if I set it in KDE Personal Settings it actually affects gnome applications. (I'm in GNOME now)

Is this known fact or a bug?
