Hi. I see that previous such topic is closed due to inactivity, but the problem still persists.
I have Brave installed with
dnf and when I choose to use QT dark style the window itself and the menu looks ok, but the settings page is white and extensions menu have dark fonts on dark background. The GTK theme doesn’t use right colors at all and looks not native.
