Default same problem

hi,
i use a lenovo thinkpad L460 with ubuntu 20.04 and dual boot windows 10 with an usb3 targus dockstation. When i use ubuntu 20.04, I have the same problem if I close the laptop screen. In mirror or extended mode, no slowdown.
Under windows, no problem whatever the mode used.
