Translucent Image Appears Blocky

This is a bug specific to my app: "DD & Daddy's Big Night Out"
Page Title: Page 11 – There is a translucent “window” that scrolls down between the driver and passengers. In the builder it works fine. On the iPad the window PNG image is blocky after the linear animation starts.  This image as imported from Photoshop with the other objects on the page.
