I’m having this same issue. Have you found a resolution? It seemed to work fine on 3.7.1 but after I upgraded to 3.8 I noticed the logo getting squished. http://037b63d.netsolhost.com/paleo/wp-login.php
I’m not using any custom CSS on the login or registration page. The logo looks normal when viewed from the Plugin Settings page. It’s 303 px wide but is being squished to 80px.
