This effect is often called <strong>ghosting</strong> or <strong>smearing</strong>. It can make motion look less clear even when the animation itself is running smoothly.</p> <p>The key idea is that refreshing the screen and changing each pixel are related but different jobs. A display may receive a new image on time while some pixels are still moving toward the brightness or colour that the new image requires.</p>
