Blurry toasts (by default)

Thanks for a very good looking library.

It is really the first thing you can see when visiting your demo.

This is in Webkit Chrome on my Ultrawide 1440p monitor. You can see that only the first (most recent) message is sharp, and the text of those below it is a bit blurry.

-webkit-font-smoothing doesn't help. Is there a way to fix this?
