    Description

      void MyClass::wheelEvent(QWheelEvent *event){
       std::cout<<event->pixelDelta().y();
      }

      is always 0 when run under wayland. If X11 is used, then correct value is returned.

      If you have problem reproducing this, I will gladly provide more information, since I can reproduce this 100% when under wayland and 0% when on X11.
