User blog comment:Rupert Giles/Global Navigation January Update/@comment-452-20150205134929/@comment-4962933-20150206053749

I altered CSS to fix this for myself: /*Global Nav Bar - Allow Square Avatar*/ .AccountNavigation .account-navigation-first-item .avatar-container { overflow : visible !important; }

This is added to Special:Mypage/global.css and affects all 1.10 Wikia wikis.

Now if only I knew how to change the name of the wiki in the search bar...

Edit: Just noticed the comment about others' avatars in notifications -- this may not address that issue.
