Currently the problem is only when moving a selection, leaving an "invisible thing" as if something were still there

When I select and move an object, it leaves a "trail" similar to alpha colors, too transparent, just where I had made the selection before, when seeing with the color selector, it makes clear that there are no alpha colors, anyway it would be a bug. I leave here the video to verify it, if it is an error of mine in which I have not noticed, please tell me, thanks. https://mega.nz/#!pNEmxQSI!RegkoWjF-N27zpW1Lp8sdneMGEXNJOXMUtASx6SvM40
