Make sure you scale the image properly before you pass it to the Scroller constructor. If you continue to have issues, please show the class codes of the scrolling world so that it can be examined. Or better yet, upload what you have (with source included) so that it can be properly tested and diagnosed. One thing it might be is that you have transpencies in your image. Make sure you use a jpeg image or, if it is a png, try drawing the image on a completely painted image (probably of color white) of the size required and using it.
