Hi Ted, I was experiencing this too! Your fix worked for me... disabled zoom: no more trails.
I seemed to only get the on the desktop background ... each set of trails would clear themselves after a second or two, and they seem to be flickering a bit, so perhaps they are only appearing in the display buffers. Maybe to do with NVidia proprietary drivers?
