gnome-shell keeps slowly consuming more memory and cpu, at 2,2 GiB memory occasional hiccups are noticeable

at 7 GiB memory consumption for gnome-shell freezes are really noticeable

this was under wayland even with amd-gpu-stack uninstalled, testing x-server right now

Please start by uninstalling these extensions:

and then log in again. Does the problem still happen after that?
