title: blinking images on hover with css transition and opacity
body: <p>does anyone know why on webkit browsers (chrome, opera), images on hover are blinking? This case is only on second column. There is an example <a href="http://codepen.io/anon/pen/fxJAk" rel="nofollow">http://codepen.io/anon/pen/fxJAk</a></p>
  
  <p>How can I fix it? Is it only webkit browsers bug? It works properly on firefox and even on Internet Explorer 11.</p>
  
  <p>It's on chrome Version 33.0.1750.146, Opera 20.0.1387.64 </p>
