Ok so thanks to your message, I have be able to dig into this a bit. By default I use hintslight (10-hinting-slight.conf is linked into my /etc/fonts/conf.d), but the font that bugs is Roboto, that has its own config file in /etc/fonts/conf.d, and it uses hintfull. So I've edited this file directly, and every other value stops the jittering for me (it does not stop some weird spacing though, for instance sometimes the "i" is to close one of its sibling). So I'm wondering: what is the correct fix here? Is this a config bug and I should raise the issue to the fontconfig package mainteneur? A font issue? Or a firefox one? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883369 Title: Weird font rendering on certain website with firefox To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1883369/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
