WordPress 4.2.1 [ADMIN BAR ERROR]

Hey I’m just pointing out a new problem with the Admin Bar that happen once WordPress updated last night.

The avatar displays in full on the admin bar and also the links e.g Howdy, are all dropped down even when your not highlighting it.
..
UPDATE!
My problem was related to the gravatar: simple set this back to default under your [SETTINGS TAB]

/* Custom Gravatar Support
/*——————————————-*/
if( !function_exists( ‘mts_custom_gravatar’ ) ) {
function mts_custom_gravatar( $avatar_defaults ) {
$mts_avatar = get_template_directory_uri() . ‘/images/gravatar.png’;
$avatar_defaults[$mts_avatar] = ‘Custom Gravatar (/images/gravatar.png)’;
return $avatar_defaults;
}
add_filter( ‘avatar_defaults’, ‘mts_custom_gravatar’ );
}
