Actually this does not affect just the richtext stuff. I just noticed that normal buttons are also affected. (please check the play button)

Indeed, this will impact all text as it's rendered in the same pipeline. Looks like something to do with wide fonts though - headers or bold text. I see this on my system too.

Should be fixed by the move to go-text renderer in v2.3.2:

Thanks Andy! Is this currently available in the develop branch to test it out?

[andydotxyz]

It's not landed yet, but you can test my PR if you like #3633

[alexballas]

Just mentioning it also here for visibility. Current develop branch is still affected by the issue even after the PR above was merged.

I was going to hold this open as not fixed, but the workaround is pretty solid ;) in v2.3.2
