Background image jumps when address bar hides iOS/Android/Mobile Chrome
...
This issue is caused by the URL bars shrinking/sliding out of the way and changing the size of the #bg1 and #bg2 divs since they are 100% height and "fixed". Since the background image is set to "cover" it will adjust the image size/position as the containing area is larger.
