That's when the interlacing doesn't happen correctly. Ideally the deflection circuits should get the raster lines of one field fall between the other field's. But sometimes the sync separate circuit doesn't do a good enough job of getting the horizontal out of the vertical, or some other circuit (maybe B+ bypassing) lets some horizontal get into the vertical.
