Toujours pareil !
Ça fait 15 ans que j'utilise Linux et je suis toujours plus ou moins arrivé à régler les problèmes ou au moins comprendre pourquoi ça ne fonctionne pas toujours mais là, je sèche...
Surtout la config de KDE, il y en a dans ~/.kde et dans ~/.config/kdeglobals
J'ai comme l'impression que le modèle de couleur est celui de KDE4 malgré la configuration de KDE5.
Ci-dessous le contenu de ~/.config/kdeglobals
