In Xorg sessions, desktop icons flicker when entering the overview

[Daniel van Vugt]

In Xorg sessions, desktop icons flicker when entering the overview.

I think this is a combination of a new feature in DING:

  https://gitlab.com/rastersoft/desktop-icons-ng/-/commit/6ab838e832b3771

and an old problem where desktop icon fading is only implemented for Xorg sessions, as shown in:

  https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1395
  (see also https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1070)

If DING intends to make the icons vanish immediately then also fading them in Xorg sessions may be causing them to disappear and then reappear to fade out.

Also assigned to gnome-shell because upstream would likely be very happy to delete the fade-out logic. It's been unused since nautilus-desktop was retired.
