Font got really small in some windows

in the options and torrent dialog window. the font got really small. all other text is good. is it a bug or a setting that got changed somehow

I have this exact same problem. I have no idea why it happened either.

EDIT:
I've checked and it's only in the Windows version for me, Linux version looks like normal.
Also, when I change to a custom theme the text gets back to normal size, so I'm guessing it's an error in the standard theme.
