Aah, now I remember. This is https://gitlab.freedesktop.org/fontconfig/fontconfig/-/issues/362 and the suggested new FontConfig keyword 'namedinstances' has been added to version 2.15. For the time being, please modify `99-lilypond-fonts.conf` as suggested in that issue; I'll submit a PR that adds this automatically to LilyPond if FontConfig >= 2.15 is found on the system. Werner
