Actually, I just found out that "Latin Modern Math" is inherently completely broken. If I set it in gedit, even the ASCII chars have ridiculous ascent/descent. So "Latin Modern Math" is basically unusable unless a program specifically modifies ascent/descent, like I did. The reason gedit was working fine previously is that it never used "Latin Modern Math", it used some other font. So it makes sense to "fix" a font that is common and inherently broken.
