Artefacts in "free rows" below the tree after dragging

[kleopatra]

reason is that the cell isn't cleared if empty or null item. to fix insert:

        protected void updateItem(TaskNode item, boolean empty) {
            super.updateItem(item, empty);
            // clear cell
            if (item == null || empty) {
                setGraphic(null);
                setText(null);
                return;
            }
            ...

Thanks- I noticed the artifact also. Unfortunately the change doesn't fix it. This seems to be some sort of focus rectangle, separate from the selection. I've not found a way to clear this...
