title: radial Gradient banding issue
body: <p>I used a css generator to create</p>
  
  <pre><code>background: radial-gradient(ellipse at center, rgba(49,35,174,1) 0%, rgba(125,72,195,1) 50%, rgba(125,72,195,1) 50%, rgba(201,109,215,1) 100%);
  </code></pre>
  
  <p>It is not displaying correctly. The gradient is rendering as stripes of the two colors. Is there a way to fix this?</p>
