That's very peculiar. What datatype are you contouring? (With the reader selected in the pipeline browser, go to the information tab, what does the "Type" field say?) Also after generating the iso-surface, open the statistics inspector (View | Statistics Inspector). What is the size of the geometry generated from the contour filter. If that's not too large, you try doing local-rendering (go to Edit | Settings, on the Server page, uncheck Remote Render Threshold). Does that help? This will help diagnose if the issue is with rendering or with the data generated by the contour filter itself.
