This bug only appears on Gnome with Wayland. It does not affect Gnome on xorg.

After the screen stays off and locked for some time the wallpaper on the main display turns black. It never happens on the secondary display.

The issue is also reported, here on gitlab: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3206
