Comment exclure la barre des tâches de Fluxbox de Compton (shadowing) ?

J'utilise Fluxbox comme gestionnaire de fenêtres et je souhaite utiliser Compton comme compositeur. Mais je ne parviens pas à exclure la barre des tâches de Fluxbox des effets (d'ombre) de Compton.

Comment puis-je faire en sorte que Compton ignore la barre des tâches de Fluxbox, notamment pour son effet d'ombre ? Dans l'état actuel des choses, la barre des tâches a constamment le même aspect visuel qu'une fenêtre inactive.

C'est ce que j'ai obtenu dans mon compton.conf :

# Shadow
shadow = true; # Enabled client-side shadows on windows.
no-dock-shadow = true; # Avoid drawing shadows on dock/panel windows.
no-dnd-shadow = true; # Don't draw shadows on DND windows.
clear-shadow = true; # Zero the part of the shadow's mask behind the window (experimental).
shadow-radius = 10; # The blur radius for shadows. (default 12)
shadow-offset-x = 5; # The left offset for shadows. (default -15)
shadow-offset-y = 5; # The top offset for shadows. (default -15)
shadow-exclude = [
    "! name~=''",
    "name = 'Notification'",
    "name = 'Plank'",
    "name = 'Docky'",
    "name = 'Kupfer'",
    "name = 'xfce4-notifyd'",
    "name *= 'VLC'",
    "name *= 'compton'",
    "name *= 'Chromium'",
    "name *= 'Chrome'",
    "class_g = 'Conky'",
    "class_g = 'Kupfer'",
    "class_g = 'Synapse'",
    "class_g ?= 'Notify-osd'",
    "class_g ?= 'Do'",
    "class_g ?= 'Cairo-dock'",
    "class_g ?= 'Xfce4-notifyd'",
    "class_g ?= 'Xfce4-power-manager'",
    "_GTK_FRAME_EXTENTS@:c"
];

# Fading
#fading = true; # Fade windows during opacity changes.
#fade-delta = 5; # The time between steps in a fade in milliseconds. (default 10).
#fade-in-step = 0.03; # Opacity change between steps while fading in. (default 0.028).
#fade-out-step = 0.03; # Opacity change between steps while fading out. (default 0.03).
# no-fading-openclose = true; # Fade windows in/out when opening/closing

#detect-rounded-corners = true;
### highlighted top window rest dimmed
inactive-dim = 0.2;
inactive-dim-fixed = true;

# Window type settings
wintypes:
{
  tooltip = { fade = true; shadow = true; };
};

Et la commande utilisée pour lancer Compton est :

compton -C -G --config ~/.config/compton.conf
