--- Comment #2 from Alexandre Demers alexandre.f.demers@gmail.com --- Well, after playing a bit more, I should say that the culprit commit only intensify the problem (generalize it to all a whole character). Otherwise, prior to that commit, it seems some parts of characters are not rendering correctly. I'm bisecting to identify when and which was the first problematic commit.
