Hi Louise, Another option with the current binaries that you have is to ask for offscreen rendering in the code (Python). The window will still pop-up but will be black and the correct rendering pixels will be send to the web client.
Just add those 2 lines simple.GetRenderView().UseOffscreenRenderingForScreenshots = 1 simple.GetRenderView().UseOffscreenRendering = 1 After the line https://github.com/Kitware/visualizer/blob/master/server/pvw-visualizer.py#L200 but in the Python script you use to start Visualizer.
