Have a look at this user's network profile. The profile picture is overflowing.
While his Stack Overflow profile looks fine. Please fix this.

The reason is
<div class="user-avatar"> has
width: 128px; and the image itself is 200px wide. So the text is not overflowing avatar's div, but image inside that div is too wide for it's container.
Stack Overflow uses
overflow: hidden; on the avatar container div, so image is clipped and the right side of it is simply not visible. Network profile does not have this set.
