( This has been asked before, many times, I know. However, it seems to have been caused by different things each time. I have gone through about four different StackOverflow answer threads and tried everything. Nothing seems to be working anymore, so I believe this is a new problem. )
Anyway, I have an HMTL element with a background image that needs to be fixed, using background-attachment:fixed;
I've spun the problem into a more simple replicable test, which is a single section
element, set to200%
of the page height, with the background being full-screen and fixed.
For easier testing on your smartphone than a code snippet: http://jsfiddle.net/LerLz1L2/
backface-visibility: hidden;
-webkit-backface-visibility:inherit;
-webkit-transform: translate3d(0,0,0);
position:static
