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: https://texdoc.org/serve/latexmk/0 Firefox can correctly render fonts with different weight while Evince will produce equal-weight result. 在 2023-01-09星期一的 13:28 -0500,Ben Cotton写道: > https://fedoraproject.org/wiki/Changes/Noto_CJK_Variable_Fonts > > This document represents a proposed Change.
