Я опаздываю на вечеринку, но это (невероятно) все еще проблема с 11.05.2017. Вот простое решение, которое также будет работать кросс-платформенно с линейными градиентами:
.backgroundFixed {
background: linear-gradient(160deg, #2db4a8 0%, #13af3d 100%);
background-size: 100vw 100vh;
position: fixed;
top: 0;
left: 0;
height: 100vh;
width: 100vw;
z-index: -1000;
}
