The e-shutter captures light scanning as an old TV set created an image - which leaves time for a fast movement to trigger the effect. It is the one shutter that is used when shooting in silent mode. Hence my question. The phenomenon may also happen when the e-shutter supersedes the mechanical one i.e. for speeds above 1/4000 if I remeber well. The rest is chronophotography.
