> I found the ugly rendering is also persistent (not just on hover) on some websites
Yes, one of those websites is the demo version of codimd (https://demo.codimd.org, in the preview pane). It is not *always* bad though, but it eventually gets there, and then it stays ugly. > local font rendering settings (freetype prefs etc) may be part of the formula, as well as whatever the sites are doing in their css/js. I can test some other local settings if you want. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1883369 Title: Weird font rendering on certain website with firefox Status in Mozilla Firefox: Confirmed Status in firefox package in Ubuntu: New Bug description: When hovering some elements, some letters moves slightly. A gif explains better than words here: https://trancart.eu/lutim/l7qWMFQF/7Q9YJRUn.gif I reproduce this at least on twitter and gitlab.com, but I remember having it on other websites. My OS: kubuntu 20.04 Reproduced on both firefox dev edition and firefox from apt package. Sorry in advance if it is not the correct place, I have no idea where to report that.
