[vtkusers] mouse flicker after vtkWindowToImageFilter

[Zisik, Herbert]

Hi all,
I'm new in programming with VTK. I use the following code to save the render
window as image:

//**************************************************************************
****************
	renderWindow->OffScreenRenderingOn();

	vtkWindowToImageFilter* w2i = vtkWindowToImageFilter::New();
	w2i->SetInput( renderWindow );
//	w2i->Update();

	vtkJPEGWriter* jpegw = vtkJPEGWriter::New();
	jpegw->SetInput( w2i->GetOutput() );
	jpegw->SetFileName("whatever.jpg" );
	jpegw->ProgressiveOn();
	jpegw->SetQuality( 100 );
	jpegw->Write();

	jpegw->Delete();
	w2i->Delete();

	renderWindow->OffScreenRenderingOff();
//**************************************************************************
****************

But there is a side effect: After them the mouse cursor flickers on the
render window when pressing the mouse button. Exists there a solution but I
don't now it?

I request for help.
