@alissonlauffer "QT_QPA_PLATFORMTHEME=fusion" shouldn't do anything, fusion is not a platform theme but a style. Also, krita hardcodes the fusion style already. Wnat is the output of "env | grep QT"?
Removed kvantum. Problem stays.
User and Kvantum have nothing to do with this library incompatibility. It looks like Plasma and KDE stuff must be rebuilt against the new version of Qt.

QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_QPA_PLATFORMTHEME=qt5ct
Removed qt5ct package and KDE works like charm!
