I'd echo Caolan's ask - we need to match what the system is doing; annoyingly
my panel / pixel ordering is not the same as yours - so the text looks terrible
anyhow. Do you see noticable false-coloring too ? If so perhaps your options
are busted as well. It also appears that in the new "no settings" world the
setting to tweak this has disappeared - most odd.

It seems that gtk+ gets those from the settings:

gtk/gtksettings.c-  g_object_get (settings,
gtk/gtksettings.c-                "gtk-xft-antialias", &antialias,
gtk/gtksettings.c-                "gtk-xft-hinting", &hinting,
gtk/gtksettings.c-                "gtk-xft-hintstyle", &hint_style_str,
gtk/gtksettings.c-                "gtk-xft-rgba", &rgba_str,
gtk/gtksettings.c-                NULL);

Which it seems come from various XSettings, which come from:

gnome-settings-daemon/plugin/xsettings/gsd-settings-manager.c
(xft-settings-get):

        order = g_settings_get_enum (manager->priv->plugin_settings,
FONT_RGBA_ORDER_KEY);

Where order is from dconf at:

org/gnome/settings-daemon/plugins/xsettings/

#define FONT_RGBA_ORDER_KEY   "rgba-order"

Which can be tweaked in dconf-editor to any of the value of that enumeration
provided: which may perhaps help (if you're running GNOME).

Now - IIRC, Cor runs KDE - so ... perhaps this is also an issue; I wonder if
gtk+ is relying on getting it's sub-pixel order from an XSetting that KDE is
simply not providing - if so, it's rather a more problematic problem.

But - as Caolan says - we can tell that from seeing a screenshot of gedit on
the same desktop quite easily ;-) give us a full-screen screenshot as a
straight attachment with gedit and LibreOffice side-by-side if you would :-)

Thanks !
