Scrolling the page background images jittering in IE and Edge

Hi,
Sorry for the late reply, I have taken a look at your page and researched the issue, it seems that this has been a MS issue for a while but I may have found a solution using javascript, only I can’t test it on my localhost due to a different MS issue, so, Please include FTP access in the Private Content area so I can try adding the javascript to your site to see if it helps.

Best regards,
Mike

Hi,
Thank you for the FTP access, the script in the article was almost correct, but I managed to adjust it so it would work. Please clear your browser cache and check.

This is what I added to your child theme functions.php:

//disable smoth scrolling error on edge causing jumpy fixed images
function disable_smoth_scrolling_error_edge(){
    ?>
    <script>
    (function($){
  $(document).ready(function(){
    if(navigator.userAgent.indexOf("MSIE")) {
        $('body').on("mousewheel", function () {
            // remove default behavior
            event.preventDefault(); 

            //scroll without smoothing
            var wheelDelta = event.wheelDelta;
            var currentScrollPosition = window.pageYOffset;
            window.scrollTo(0, currentScrollPosition - wheelDelta);
        });
} else {

}
});
})(jQuery);
  </script>
  <?php
  }
  add_action('wp_footer', 'disable_smoth_scrolling_error_edge');
