The second image is because of the <img /> tag. you need to hide the img in your styles.css file:
.App {
font-family: sans-serif;
text-align: center;
}
.hidden {
display: none;
}

src. It draws the image on canvas, when the image is loaded. check out img.onload in your componentDidMount method.– Masious
