Bonjour à toutes et à tous,
Je vous contacte après avoir lu les quelques posts existants à ce sujet mais sans succès.
Depuis que j’ai mit à jour l’ensemble de mes paquets, Plank n’arrive plus à détecter quelle application est ouverte ou non, et crée donc une nouvelle instance de cette application lorsque je clique sur son icône au lieu de juste l’agrandir (ou réduire).
Je ne sais pas si je suis un cas isolé ou si ce problème est récurrent, mais un grand merci à toute personne qui saura m’apporter une piste 
(Dites moi si vous préférez que je mette la retour du lancement de plank hors d’un texte préformaté)
Mon système :
Debian 11
Plasma KDE/Gnome
Ce que j’ai déjà fait :
Purge et réinstallation de Plank
Purge et réinstallation de bamfdaemon
Voici ce que retourne le lancement du programme en mode debug :
