All custom fonts look like a disaster on Chrome in Windows. It's the only browser that uses GDI to render text in Windows where Firefox/IE use DirectDraw. All fonts end up being rendered very thin, and if they're thin to start with, that causes discontinuities in the glyphs. It also affects the color; the rendered color may be significantly different than the text color specified in CSS.
It's been an open bug on Chromium/Chrome for several years.
