The Loading Animation settings allow you to specify an alternate animation image, position, and size for the loading animation. The loading animation appears briefly every time a new screen is rendered while the application is being used. In Profound UI 5.8.0 and prior, the default animation is a spinning circle that appears in the top-left corner. Starting with Profound UI 5.9.0 and later, the default animation is two semicircles spinning in the top-left corner and is created with CSS.
