[vtkusers] Blurred images using QVtkWidget

[Martin Baumann]

Hi,

I am experimenting with QVTKWidget and have the problem that
images that are rendered by the render window of the QVtkWidget
are looking blurred.
Until now I used a plain vtkRenderWindow and the rendered images
had sharp edges when visualizing meshes for instance. I already
changed the Smoothing options of the render window but this
didn't help.

What could cause this problem?

Best regards,
Martin Baumann
