PDF Output for Math blocks

[YimingZhang07]

Hi hello,

This is not really an issue for Github theme, but just when I export the document into PDF on Windows10 with the latest Typora, the Github theme seems to export with a larger font size of the math blocks, while other themes will have very small sizes which makes difficult to read. I just want to ask what might be the problem is and how you did to make Github theme good.
Attachment is a comparison, same formulas, one using "paper" theme in the gallery, the bigger font size on is the "GitHub".

This really confused me and hope you could reply.
