Hide "title" on mouseover in avia_sc_slider_full (fullwidth image slider)

if these are only images that are not meant to be opend in a lightbox – you can simply remove the titles of the images.
This is not an enfold setting – it is simple browser behavior to show after a while the title on hovering.
just put it in the child-theme functions.php:

function remove_title_attr(){
?>
<script>
(function($) {
  $(window).on('load', function(){
    $('*[title]').removeAttr('title');
  });
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'remove_title_attr');

If you need the title for lightbox bottom-bar description – use instead:

function temporary_removal_title_tags(){
?>
<script>
  window.onload = function() {
      var links = document.querySelectorAll('a,img,div[title]');
      for (var i = 0; i < links.length; i++) {
          var link = links[i];
          link.onmouseover = function() {
              this.setAttribute("data-tooltip", this.title);
              this.title = "";
          };
          link.onmouseout = function() {
              this.title = this.getAttribute("data-tooltip");
          };
          link.onmousedown = function() {
              this.title = this.getAttribute("data-tooltip");
          };
      }
  };
</script>
<?php
}
add_action('wp_footer', 'temporary_removal_title_tags');
