title: Firefox linux (centos) responsive design image scaling
body: <p>I have an arrow in circle. <img src="https://i.stack.imgur.com/GvJMR.jpg" alt="enter image description here"> CSS:</p>
  
  <pre><code>img{
          float:left;
          width: 15%;
          max-width: 33px;
          height: auto;
      }
  </code></pre>
  
  <p>In windows xp (ie8,safari,opera,ff,chrome) I checked everything is ok. The image is getting bigger and smaller - no any lines. But in linux  some lines appear from the right and at the bottom of the picture. I checked image several times - there are no any lines. How can it be fixed?</p>
