    Description

      Toggling between the two tabs of the example application below causes flickering of the application in case Aero is enabled. (It might not flicker with each tab change.)
      With windows classic no flickering occurs.

      main.cpp
      
#include <QApplication>
#include <QTableWidget>
#include <QGLWidget>

int main( int argc, char** argv )
{
  QApplication instance( argc, argv );

  QTabWidget tabWidget;
  QGLWidget glWidget1;
  QGLWidget glWidget2;
  tabWidget.insertTab( 0, &glWidget1, "1" );
  tabWidget.insertTab( 1, &glWidget2, "2" );
  tabWidget.show();
  QObject::connect( &instance, SIGNAL( lastWindowClosed() ), &instance, SLOT( quit() ) );

  return instance.exec();
}

      Not tested with other Qt versions.
