--- Comment #1 from Chiitoo escomk3@hotmail.com --- As an additional note, though it may be obvious to some already, since there is a noticeable effect on the performance without the mentioned commit as well, I imagine it's possible that the actual issue is only exacerbated by said commit.
In that sense, this might not be regression per-se, but instead, just making an already existing issue more noticeable.
Or the issues might be completely separate, of course. :]
