           Summary: Subpixel rendering options aren't only for hinting
           Product: Xfce
           Version: 4.1.99.3 (4.2RC3)
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: Low
         Component: xfce-mcs-plugins
        AssignedTo: xfce-bugs at xfce.org
        ReportedBy: ats-xfcebugs at offog.org


I'm one of those weird people who dislike hinted text rendering. XFCE works fine
with hinting disabled, except for one little niggle:

In ui_plugin's interface, there's an option to select the subpixel colour order
of your display. It's labelled as "Use sub-pixel hinting", and is only available
when hinting is enabled.

This is awkward because subpixel rendering is also used for unhinted text. If
you enable hinting, turn on subpixel rendering, then disable hinting, you'll get
unhinted text with subpixel rendering (as you'd expect), but you then can't
disable subpixel rendering again without turning hinting back on temporarily,
and you can't turn it on in the first place without also turning on hinting.

The relevant code is in plugins/ui_plugin/ui_plugin.c. As far as I can see, all
that needs doing to make it possible to toggle subpixel rendering when hinting
is off is to replace the string "Use sub-pixel hinting:" with "Use sub-pixel
rendering:", and remove the calls to gtk_widget_set_sensitive(...->aa_checkbox3,
...).

Alternately, if the intention was to force subpixel rendering on the display to
be disabled when hinting is off (which isn't entirely unreasonable, given that I
think it looks ugly, but I could imagine other people wouldn't), then
apply_xft_options should instead be changed to force current_xft_rgba to "none"
if !current_xft_hinting.

Thanks!
