I am trying to move this selection for use elsewhere, but dragging, copying, and cutting all produce this same strange result of leaving pixels behind. You can see parts that are definitely within the selection not moving with the rest. I know the edges are not very clean, but that doesn't matter too much to me. I added a contrasting background so you can see the affected areas better. How can I resolve this?
I do have other layers, but none of them are anywhere near this part of the image.
