Kubuntu 20.04, since upgrading kernel from version 5.8.0-48.54 to version 5.8.0-49.55 the system boots properly but the GUI often hangs, either immediately after user login to GUI or any time after that (screen stops updating with various artifacts and UI no longer responds) and computer has to be restarted.
