In recent days I've been working on a website that uses simple parallax effects (fixed images).
It stopped working very recently.
I currently use Google Chrome, and before checking other navigators I even thought it was due to Chrome's update released yesterday.
However, I've tested it in IE, Edge, Firefox and Opera, and it only works in IE and Edge (laggy, but still works).
I've also tested other Webflow templates that uses fixed images, and they're not working either.
