Hello Daniel! I had one extension active (User Theme) for getting the dark theme truly dark everywhere. I checked top and it is gnome + shell that push the cpu up to over 80% - but only in short bursts. I made two journal files just in case - I'll attach them. Thank you so much for your help! If there is anything more I can do to help out, please let me know Kind regards Jofen Kihlstrom On Mon, 22 Jun 2020 at 08:01, Daniel van Vugt
