title: Mix-blend-mode bug on text
body: <p>I am working on a knockout text using <code>mix-blend-mode</code> property. When I open the console to use Developer tools to test responsiveness, there are little lines that appear and disappear above and below of the blended text. On every selection, I do on the device selector of the developer tools console, this bug is presented. These are some examples:</p>

  <p>This is the code I use to create this text:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.backdrop {
    background: url("https://rpsthecoder.github.io/img-repo/Taitō%20by%20Jezael%20Melgoza.jpg") center;
    background-size: contain;
    margin: auto;
    margin-top: 40px;
    width: 75vw;
  }
  
  .text {
    font: bolder 20vw "Arial";
    text-align: center;
    margin: 0;
  }
  
  .screen {
    color: black;
    mix-blend-mode: screen;
    background-color: #fff;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="backdrop"&gt;
    &lt;p class="text screen"&gt;Taitō&lt;/p&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I notice that this bug does not happen when you run the code on <a href="https://codepen.io/lvidal/pen/gOOVENM" rel="nofollow noreferrer">Codepen</a> and I could not figure out why is that. However, it can happen on a simple static HTML file.</p>
  
  <p>I tried to use <code>will-change: opacity</code> described <a href="https://stackoverflow.com/questions/30479321/chrome-css3-mix-blend-mode-bug-in-chrome">here</a> and <a href="https://stackoverflow.com/questions/51140449/mix-blend-mode-doesnt-work-on-chrome">here</a>, but I had no luck.</p>
  
  <p>My chrome version is <strong>Version 78.0.3904.108</strong>. This bug only happens on Chrome. I would appreciate it if anyone can give advice about this.</p>
