Scrrenshot of package and git FreeType font rendering
Description of problem:
I usually compile from source to stay up to date. Tried the new
ClearType-enabled package and got strong color fringing that I don't see in
vanilla source builds.
Version-Release number of selected component (if applicable):
2.9.1-6
How reproducible:
1. Turn on subpixel rendering in GNOME Tweak Tools, restart GNOME shell and
look at fonts.
2. Compile freetype from upstream source and LD_PRELOAD it for Firefox, etc.
Actual results: See screenshot.zip -> package.png
Expected results: See screenshot.zip -> git.png
Also:
I don't think you need freetype-2.9-ftsmooth.patch. I don't even think you need
to define the SUBPIXEL_RENDERING option at all, since FT comes with a different
and maybe not patent encumbered subpixel rendering method by default and I
couldn't tell the difference in quickly switching screenshots.
