Bug#1085760: OOM when opening background panel

[Guido Günther]

Package: gnome-control-center
Version: 1:47.0.1-2
Severity: grave

Hi,

opening the appearance panel on "low" memory devices (e.g. a Librem 5 with
3GB) makes g-c-c hit OOM as it spawns about a dozen jxl decoders for
thumbnailing.

I've picked grave severity as hitting this situation on such a device
renders it mostly useless as on the next startup the same panel is
opened again and the same crash happens. This can only be resolved by
going to the command line and using

   gnome-control-center <some-other-panel>

(feel free to lower the severity though if you see fit).

The MR at patch https://gitlab.gnome.org/GNOME/gnome-control-center/-/merge_requests/2850
fixes this and is targeted for 47.1

Cheers,
 -- Guido
