Hi,

Seems that some changes mentioned below just hit
fedora:fedora/38/x86_64/testing/silverblue today in version
38.20230314.0. And ostree diff is below (changes between 38.20230313.0
and 38.20230314.0, filtered to show only fontconfig files for CJK):

D    /usr/etc/fonts/conf.d/65-0-google-noto-sans-cjk-ttc.conf
D    /usr/etc/fonts/conf.d/65-google-noto-cjk-fonts.conf
D    /usr/share/fontconfig/conf.avail/65-0-google-noto-sans-cjk-
ttc.conf
D    /usr/share/fontconfig/conf.avail/65-google-noto-cjk-fonts.conf
A    /usr/etc/fonts/conf.d/65-0-google-noto-sans-cjk-vf-fonts.conf
A    /usr/etc/fonts/conf.d/65-google-noto-sans-cjk-mono-vf-fonts.conf
A    /usr/etc/fonts/conf.d/65-google-noto-sans-cjk-vf-fonts.conf
A    /usr/share/fontconfig/conf.avail/65-0-google-noto-sans-cjk-vf-
fonts.conf
A    /usr/share/fontconfig/conf.avail/65-google-noto-sans-cjk-mono-vf-
fonts.conf
A    /usr/share/fontconfig/conf.avail/65-google-noto-sans-cjk-vf-
fonts.conf

But I am noticing some font being very thin, including English fonts in
Evince when not using embed fonts and all non-UI text in Telegram (both
Evince and Telegram is installed from flatpak). 

I don't know if this should be considered as a bug from this change or
just several applications not being compatible with VF fonts and should
be reported to their upstream separately.

Cheers,
Qiyu Yan

This is an example of a random PDF file not being rendered correctly:

Firefox can correctly render fonts with different weight while Evince
will produce equal-weight result.
