How to remove jerking in IE?

Question

css

There is a block on the site with such properties, the essence of which is to create the effect of finding the block under other blocks. Example - joomshaper.com , 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%;

It works fine in all browsers, but in IE there is a twitching of the picture. How can I fix it?

Answer 1

Remove IE :)
