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

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 youtube.com 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 youtube.com.

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!
