A lot of sets don't have the capability to show a sharp cutoff without a smear. However, if there are leaky caps in the video detector circuit, it could cause or worsen that. Also a weak video detector tube could cause it. Also, of course a slightly gassy CRT can cause a slight smear, or a bleeding or flaring. But keep in mind that some smear is normal in vintage TVs. In the old days, broadcasters were careful not to put sharp, contrasty things in the picture.
