Re: How to set latex preview font to regular instead of italics?

I ended up with DejaVu Math TeX Gyre. You probably need this font 
installed on your system, but I'm not sure, because I had it installed 
before. Here's code to replace in my config:
  \\usepackage{mathastext}
  \\usepackage{unicode-math}
  \\setmainfont{Liberation Serif}
  \\setsansfont[Scale=MatchLowercase]{Liberation Sans}
  \\setmonofont[Scale=MatchLowercase]{Liberation Mono}
  \\setmathfont{DejaVu Math TeX Gyre}
