https://bugzilla.suse.com/show_bug.cgi?id=1223434 Bug ID: 1223434 Summary: /etc/fonts/conf.d/21-emoji-rendering.conf makes emoji rendering in Firefox worse Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Firefox Assignee: factory-mozilla@lists.opensuse.org Reporter: gerald_chen@foxmail.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 874523 --> https://bugzilla.suse.com/attachment.cgi?id=874523&action=edit With 21.conf vs without 21.conf I've noticed that emoji look weird in Firefox, as shown in the upper side of the attachment (look at those spooky triangle eyes!). After deleting /etc/fonts/conf.d/21-emoji-rendering.conf, emoji got rendered properly, as shown in the lower side of the attachment. Other applications, such as Konsole and Chromium, don't have this problem. /etc/fonts/conf.d/21-emoji-rendering.conf says that emoji fonts don't need hinting. It seems not to be the case. My fontconfig file in home directory hasn't specified hinting or hintstyle.
