Hi Louise, I have seen something like this before when using VTK render windows on Linux with NVidia drivers. There is a bug/feature in the NVidia driver where it only renders the part of the window that is shown onscreen. The workaround I used at the time was to enable offscreen rendering (which I think ParaView will do by default in the 5.5 when that is released in a few months). In ParaView master/5.5 it will be a command line option too --force-offscreen-rendering, but I think for 5.4 and earlier you would need to build ParaView with offscreen rendering enabled and then use that ParaView for Visualizer.
