[Bug 1815550] Re: gnome-shell high memory and CPU usage when using zsh

[Daniel van Vugt]

OK, that's a red flag. Those folders should not appear on your desktop.

On IRC you suggest that everything in  ~/.config/user-dirs.dirs is
pointing to $HOME/. So whatever leaks or CPU inefficiencies the gnome-
shell-extension-desktop-icons has already will be amplified on your
machine, by both:

 (a) The strange custom ~/.config/user-dirs.dirs where everything points to $HOME
 (b) The use of zsh which touches $HOME on every command.

I expect practically zero users to have (a), and larger but still small
subset of users to have (b). So we can safely lower the priority. It's
at least useful now we know how to stress test the extension for leaks
and performance.

Bug description:
  This *may* be an nvidia-specific problem, but the RSS of gnome-shell
  on my system grows without limit (over a couple of hours it's
  increased past 10G).

  At the same time, gnome-shell appears to become progressively less
  responsive.

  Restarting gnome-shell (via <Alt><F2> restart) drops shell RSS down to
  ~400MB and improves system responsiveness a bit.
