It appears the relationship between zsh and gnome-shell can be
explained:
1. zsh writes to ~/.zsh_history after each command.
2. The Modify and Change timestamps of ~ change each time.
3. gnome-shell-extension-desktop-icons monitors ~/Desktop/* but also ~
because your home folder appears on the desktop too (unless you disable
that icon in Tweaks).
4. gnome-shell has to wake up and run JavaScript code every time ~ gets
touched, which is every time zsh runs a command.
I think this is the basic mechanism for this bug. Unfortunately I still
cannot reproduce any measurable memory or CPU usage though. And there's
no evidence this is related to Nvidia at all, yet. So the next step in
debugging might have to be with Chris.
Chris, please try this:
1. Tweaks > Extensions > Desktop icons > cog wheel > Show the personal
folder in the desktop = OFF
2. Log out and in again, to be sure.
