The border-radius is incorrect. We put a style class on the input element but it probably shouldn't be there when the forgot passwords buttons aren't present. The class expects the button right next to it and styles the input to have a flat edge.
Here's some CSS to workaround it:
#sclogin-passwd, #sclogin-username {
border-radius: 0 4px 4px 0;
}
SC Login Display Cropped
