After a recent tour through Gnome3, KDE and Unity my font anti-aliasing in XFCE4 has changed in a subtle way (not sure if it was any of the DEs that changed the setting or any of the dependencies that got install when installing the DEs):
The font, Verdana 8, looks almost exactly the same, except in the old one subpixels where used to make the lines a little wider in the new one they are just one-pixel.
Which setting does cause this effect and how can I set it back? It's neither the hinting nor the subpixel ordering, which are the only settings reachable from XFCE4.
Edit: When I create a new account without any existing configuration I get the old subpixel rendering back.
