Confirming there is still an issue with the latest package for Ubuntu 20.04. I recently upgraded 20.04 and installed the latest DL package, displaylink-driver-5.3.1.34. Now if I close the lid, the UI lags 3-5 seconds on input (e.g. button click does nothing for 5 seconds). Opening the lid and the issue immediately goes away. Nothing from htop seems to indicate this is in anyway tied to CPU/memory load.
