[Bug 1599870] emojis do not render if font hinting is turned off
by bugzilla@redhat.com

--- Comment #2 from Matthew Wong <mawong(a)redhat.com> ---
Hi, yes I still see it. I made a mistake in my original report because it seems
it is not just hinting off but the combination of hinting off + antialias on in
my fontconfig file that causes the issue:
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
<match>
<edit mode="assign" name="hinting">
<bool>false</bool>
</edit>
<edit mode="assign" name="antialias">
<bool>true</bool>
</edit>
</match>
</fontconfig>
I do not use gnome DE, so I am not sure how gnome-tweaks and this fontconfig
file interact. Trying gnome, I deleted my fontconfig and used gnome-tweaks to
set hinting off + antialiasing on (subpixel) and emojis show in
gnome-characters as expected, but if I use the above fontconfig then emojis do
not show no matter the setting in gnome-tweaks or what DE I am using.

It looks like you use "none" LCD filtering from the screenshot. But it is
strange that you see this in so many different environments. I guess that you
have it set globally in a place like "/etc/fonts/conf.d/". Does any of the
files there contain "lcdnone" string?
Do you see the problem under a new user?
