clip-path leaves straight lines around my circle

Question

I used clip-path to create a circle in which my image can zoom out and a filter gets applied to it.

But for some reason straight lines are visible during the hover transition.

Wierd lines around image

.u-center-text {
  text-align: center !important;
}

.u-margin-bottom-small {
  margin-bottom: 1.5rem !important;
}

.u-margin-bottom-medium {
  margin-bottom: 4rem !important;
}

.u-margin-bottom-big {
  margin-bottom: 8rem !important;
}

.u-margin-top-big {
  margin-top: 8rem !important;
}

.u-margin-top-huge {
  margin-top: 10rem !important;

Add overflow:hidden to .story__shape

.u-center-text {
  text-align: center !important;
}

.u-margin-bottom-small {
  margin-bottom: 1.5rem !important;
}

.u-margin-bottom-medium {
  margin-bottom: 4rem !important;
}

.u-margin-bottom-big {
  margin-bottom: 8rem !important;
}

.u-margin-top-big {
  margin-top: 8rem !important;
}

.u-margin-top-huge {
  margin-top: 10rem !important;
