midnight.js is slows down

[Owlcattt]

hello, I have a fixed navigation
{

<nav class="navbar">
       <div class="container-menu">
             <a href="#" class="navbar-brand">
                  <img src="{% static '--------------------'%}" alt="" class="logo-little">
              </a>
              <div class="navbar-wrap">
                  <ul class="navbar-menu">
                          <li><a href="#">------------</a></li>
                          <li><a href="#">---------</a></li>
                          <li><a href="#">------</a></li>
                          <li><a href="#">--------</a></li>
                   </ul>
               </div>
                <div class="navbar-finder">------------</div>
         </div>
</nav>

}
And i also use swiper.js in the project and there is a rather noticeable delay when changing the text color.
