Hi,
no I'm using the qt6 version. It looks like you are using the default
window decoration on wayland, which is without shadows.
Qt6 dropped "plastique", "motif" and some other styles. Only "fusion" and
"windows" are available (and of course "kvantum" and "adwaita" if you
installed them). These are called "styles", and are .cpp Qt plugins rather
than themes; you can set them to use a custom .qss if you want to theme
them. Kvantum instead is a theme engine, and you can install themes with
it. Very linear and uncomplicated, isn't it? :)
