I’m dealing with the exact same issue, Qt5 apps on Wayland doing no integrations (specifically running QBittorrent & Strawberry). They take configs from Qt5ct, but that’s about it. Qt6 seems to work better, at least they move window controls to the left as with my GTK setup. No other Qt-related configs on my end. Are Qt5 apps just broken like that on 23.04? Any news on this?
