The last update for the skin was in October 2015, while it may not need many updates for bug fixes it would be nice to see continued development.
You can find the patch here: https://github.com/redsigma/UPMetroSkin/
Users have noticed clipping of fonts as well as jumbled areas where fonts and icons mix. Due to how Steam updates its looks on its own there is always a risk of issue if fonts or other UI elements are changed. Sadly it does not look like the dev is keeping up with these changes, which is why fonts are clipping.
