Also INFO for nvidia users. Driver 495-version spamming to dbus (and KWin too on KDE) and overflows system logs and which makes dbus consume a lot of RAM. For solve this create dbus config: /etc/dbus-1/system.d/nvidia-fake-powerd.conf

The first 5.15 kernel should be out soon for you, can you try it when you get the chance?
