--- Comment #13 from Nicolas Mailhot nicolas.mailhot@laposte.net --- I think the problem is misdiagnosed
It has nothing to do with apx itself
The problem is in the way Fedora renders (at least some) open-sans versions
I had the same horribly pixelated effect (font "pixels" as big as some dingbats), I also attributed it to bitmap fonts, wasted a lot of time hunting them down with no effect, then finally installed a firefox extension to identify the font used
To my surprise it pointed opensans and removing the opensans packages from the system fixed the problem.
Either Fedora misbuilds opensans or something in it horribly confuses the text stack or firefox
This is on a hidpi system (full hd 13" chromebook)
