The GUI responds very slow, if you click, the command of the click goes on after about 3 seconds... if you type, all the letters are with the same lag, so it is totally unusable. Was using displaylink without any problem on 19.10 until yesterday, when I upgraded to 20.04. It is terrific. If i plug out the usb for the displaylink docking station, than the speed is back, and the system is ok, if I connect it to the docking station again, everything extremely slow again. Please investigate this asap, as it is unusable on displaylink docking stations.
