When dragging a file from one dolphin window to another, the speed of the file icon does not match the speed of the mouse. So while trying to drag it, it will lag behind by several seconds, and the icon keeps moving along the original mouse path even 10 seconds later after the mouse button has been released. This happens while files are being transferred from one smb share to another. Reproducible: Always
