Same as above guys, I can confirm this issue on Lenovo X1 Carbon gen 7 notebook. Problem appear after upgrade from 19.10 to 20.04 LTS. Using ubuntu 20.04 on DisplayLink docking with an external monitor is totally unusable. The GUI responds so slow that if you click, the command of the click goes on after about 4-5 seconds. If you type, all the letters are with the same lag, so it is totally unusable. If I plug out the USB for the DisplayLink docking station, then the speed is back, and the system is ok if I connect it to the docking station again, everything extremely slow again.
