I'm building a long page that has 4 individual parallax elements. The first 2 always work as intended. The second two work on first visit, but then after navigating to another page and then back to the About Us page the last 2 parallax elements on the page are not positioned correctly and stay that way until a refresh. I have tried to troubleshoot it, but I'm not sure what is going on.

jQuery(window).load(function() {setTimeout(function() {
jQuery(window).trigger('resize').trigger('scroll');
}, 1000);
});
This bug comes from our theme and we'll fix it soon - but for now, this is the only way to fix that problem.
