Bug ID: 2212512
Summary: fontconfig package installs
10-sub-pixel-rgb-for-kde.conf by default in
/etc/fonts/conf.d
Product: Fedora
Version: 38
Hardware: All
OS: Linux
Status: NEW
Component: fontconfig
Severity: low

Target Milestone: ---
Classification: Fedora
/etc/fonts/conf.d/10-sub-pixel-rgb-for-kde.conf seems to be included with the
fontconfig package. It doesn't appear to be in /usr/share/conf.avail, where I
would expect and symlinked into conf.d.
ontop of that, it causes font rasterizing problems in some applications such as
GTK applications on KDE where the display is not using an rbg subpixel
geometry.
Users should add this to their local fontconfig and probably shouldn't be the
default.
Reproducible: Always
Steps to Reproduce:
1. Use the KDE desktop
2. Launch evolution and attempt to read email
Actual Results:
Text has extreme rainbow fringing
Expected Results:
for rgb subpixel rendering to be disabled.
I already have an existing $XDG_CONFIG_HOME/fontconfig/ and it looks like KDE's
settings application fiddles with it, which may explain why I experienced this
issue specifically, despite turning it off there. Either way, the way this file
is installed seems wrong to me given most files in this directory are
symlinked.
the, workaround/potential fix, is trivial, simply delete the file from conf.d
and the problem appears to go away.
Also:
* I have an existing installation of GNOME and installed kde using
@kde-desktop group.
* # dnf whatprovides /etc/fonts/conf.d/10-sub-pix
el-rgb-for-kde.conf
