Thank you for the provided sample.
The problem comes from the fact that content of the .img-content container overflows. As a result the user is able to scroll vertically/diagonally.
The issue can be resolved with CSS. For your convenience I updated the example: http://dojo.telerik.com/UgIR/4
Please pay attention to the CSS changes. I also fixed other issues such as incorrect binding and multiple app initialization.
