We have encountered issues with APNGs with not a factor of 4 dimensions which we switched from volatile buffers on Android to non-volatile. For some surface types, the stride will not equal 4 * width when the width is not a multiple of 4. It will add some padding on each row. This caused distortion as seen in bug 1391430. While we have fixed this, we should add a test case for it.
