So on my phone i have installed [https://github.com/github/mona-sans mona sans font] via miui themes (seems like its not caused by miui themes) I'm have tried font manager magisk module before and after knowing that it wont really work on my device, i revert to default font and uninstall it And for some reason the fonts just look like this... (everything works fine) Is there anything that can fix this? Tried method: using another version of firefox [stable,beta(current),nightly] Use revert to roboto fonts on miui themes Chromium dont have this issue There is temporary fix for it by using font changer add-ons I want it to fix without usint any add-ons
