Click and drag around a bit (release selection outside designed window) and you get this rubber marks left.

A single click on the window also leaves a rubber mark.

Dragging and then releasing the mouse button outside the scroll area causes does not cancel the drag.

I reported this already, but you appear to have deleted it!!

I've noticed this too, when you click somewhere. I had to check in the object
list to see if an actual 1x1 pixel object was created, but it wasn't. Phew!
