    For full 360 degree spherical panoramas we introduce small holes at the poles because the nadir and zenith are generally pretty unseemly (due to the spherical stretching of the source image, and degenerate triangles in the reconstruction).  We do this for both "regular" and fisheye projection but it's more noticeable in fisheye.  Perhaps we could have an option to remove them in the next version.

     

    Thanks,
