I am using a HP ZBook 15 G6 laptop which had no problem on Ubuntu 20.04.
After an upgrade to Ubuntu 22.04:
Terminal is less responsive after a few minutes: sometimes letters are displayed about 1 second after typing it on my keyboard (I use gnome-terminal and I have the same problem with terminator, I haven't tested other terminal emulators)
Nautilus is also less responsive: content of directory can be displayed several seconds after double click on it. Moreover there is some flickering when the content is displayed.
Other applications work well: google chrome, firefox, vscode, qt creator, virtual box, docker...
Any idea or debugging method is very welcome :-)
