Roboto web font not rendering properly


(Core :: Layout: Text and Fonts, defect)

Firefox 81





(Reporter: web, Unassigned, NeedInfo)



(3 files)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:81.0) Gecko/20100101 Firefox/81.0

Steps to reproduce:

load, or other site which uses the Roboto web font e.g.

Sites which use my local copy of Roboto do not seem to be affected

Actual results:

See screenshot

Expected results:

Normal font rendering

Please provide clear and self-contained steps to reproduce how exactly something is loaded somewhere - thanks!

Also, does this happen in safe mode without any add-ons enabled, in a fresh and new user profile?

"Restart with addons disabled" solved the problem for that session, until I quit the browser and restarted normally, when the problem returned. Manually disabling all extensions did not solve the problem then

This is the HAR for the request for the web font

The problem appears to have been solved in 81.0b7

WebRender seems to be enabled by default for you now, is there any chance that's why it came back?

It's possible?

a few observations:

Uninstalling local roboto fonts, then reloading changed the nature of the bug. before uninstalling and reloading, the video thumbnail subtitles were corrupted, after uninstalling and reloading the video subtitles were fine, but the video titles were corrupted.

Then, unsetting video title font-weight via dev tools fix its rendering.

Then, installing roboto locally again with the latest version from google fonts website, then restarting firefox has - so far - solved the rendering on

Perhaps the particular version of Roboto that you had installed previously tickled a WebRender bug. I'm going to mark this WFM again, but please do re-open if it comes back again, and we can try to work out what's going on with the specific font files. Thanks!
