I know this happens in the Acer Sacnwit, and can give a smeared
appearance to small bright detail against near-black backgrounds. The
appearance is as if the image has been smudged slightly to one side. The
charge persists for quite a few lines.
The newer generation of CCDs get round this by having a reset pin that
can dump all the remnant charge at the end of the shift cycle, prior to
the next exposure.
