too many renders

Steps (for linux):

• start paraview as follows: env PARAVIEW_LOG_RENDERING_VERBOSITY=INFO ./bin/paraview -dr. This will cause ParaView to output information on terminal every time ParaView does a render.
• Wavelet, Apply, Contour Apply
• Now observe the terminal and click on Wavelet1 and then Contour1 and you'll notice each time the active source changes, a render is triggered.

That should not be necessary and causes the application to feel clunky when rendering large datasets.
