How to remove the twitching in IE?

There is a block on the website with such properties, the essence of which is to create the effect of being block by other blocks. Example - joomshaper.com the first screen
background-image:url(/images/2016/04/15/First_main1.png);
background-repeat:no-repeat;
background-size:cover;
background-attachment:fixed;
background-position:50% 50%;

In all browsers works fine, but in IE happens to stumble pictures. How can I fix it?
