    Description

      WA_TranslucentBackground does not work with direct2d engine

      In our application, a top level QWidget, which is constructed with Qt::WA_TranslucentBackground, does not become visible after calling show(), when platform is "direct2d".

      The same application works perfectly with platform "windows".

      The custom widget constructor is like this:

      CMyWidget::CMyWidget()
      : QWidget( 0, Qt::WindowStaysOnTopHint | Qt::Tool | Qt::FramelessWindowHint )
      {
      setAttribute( Qt::WA_TranslucentBackground, true );
      }
