Your fontconfig is fucked. Enjoy debugging your system for the next week.

Eh, perhaps Fedora one, since I can reproduce this in Fedora 39 Live.

luk1337 commented 9 months ago

Reported bug on Fedora side instead — https://bugzilla.redhat.com/show_bug.cgi?id=2262410, since I noticed that this also affects some other apps.

astiob commented 8 months ago

I want to point out that even before the quoted change, Fedora presumably used Noto Sans Arabic as its sans-serif for users with an actual Arabic locale, resulting in appearance similar to (same as) the “broken” screenshot in this report. Perhaps sans-serif isn’t quite that safe of a default for OSD/subtitle font.

@luk1337 or any Arabic users: FWIW another way to work around this is to set an explicit osd-font in mpv’s configuration.

Still, this is another reason why libass may want to change how it sizes fallback fonts.
