iOS 9 Safari: changing an element to fixed position while scrolling won't paint until scroll stops

Question

I\'ve been developing a site and taking advantage from the rather good jQuery Sticky Kit plugin. It operates by switching the position property to fixed

Answer 1

The only solution that I found to work correctly was to disable z-index translations on direct children of the fixed item, e.g.:

.is-sticky > * {
    -webkit-transform: translateZ(0);
}
