Description of problem:
On FC3 subpixel font smoothing looks much worse than on FC2 (actually,
on FC2 it looks nice).
I have the exact same configuration (in gnome font preferences):
"Subpixel smoothing (LCDs)"
Clicking on details also shows the same settings:
Smoothing: "Subpixel (LCDs)"
Subpixel order: "RGB"
On FC2, fonts look thin and well defined with these settings, but on
FC3 they look all weird with shades of blue, yellow and red.

FC2 and FC3 subpixel smoothing comparison
Take a close look at the "sample text" and the menu text.
Actuall there is another problem there, on FC3 the text on the title bar is a
bit above the correct position. This doesn't happen with this theme only, but
I'm not sure who to blame, X or Metacity.
BTW, this may seem like nitpicking, but on my TFT its the difference
between beautiful text (on FC2) and ugly text (FC3).
Reassigning to FreeType since it has nothing to do with X.
It's probably just changes in the FreeType hinting algorithm,
unfortunately, what improves display for one font at one
size, with one set of display options, may hurt somewhere
else. There isn't necessarily much we can do about that.
it could *conceivably* be a bug in gnome-settings-daemon,
or Pango, or Xft, in getting the right options to FreeType.
From my perspective it's worse with every single font, at every single
size I've tried.
I will try to mess around with the font options in gnome, but on gdm I
see the same thing, since I've set:
I guess this could be an area where some finetuning options could be
nice. These options could be accessible only through resources or
gconf (one could someday make a wizard to help the user adjust it to
his liking, like Microsoft has for ClearType - well, in this case
ClearType just sucks, with every setting...).
Hmmm, I guess only the "sample text" is noticeably worse on my
screenshots (and I just seen them on a CRT, which seems to disguise
the problem a bit), because the other text is against a gray
background. But I can assure you that on some apps, some text apperars
all colorful... :)
Taking a CVS snapshot of freetype2 and building with the bytecode
interpreter enabled is an improvement on the freetype 2.1.9 packages
included in FC3, IMHO.
Problem gone. I had a ".font.conf" file on my home dir. I deleted it
and everything's fine now. I don't know where the hell that came from
It came from KDE Control Center... Annoying...
