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 Assignee: tagoh@redhat.com Reporter: anthony@dedominic.pw QA Contact: extras-qa@fedoraproject.org CC: ajax@redhat.com, fonts-bugs@lists.fedoraproject.org, gnome-sig@lists.fedoraproject.org, i18n-bugs@lists.fedoraproject.org, mclasen@redhat.com, pnemade@redhat.com, rstrode@redhat.com, tagoh@redhat.com 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.
