Hi Ufuk, I haven't heard of any issues like this. Do you get similar behavior on the machine when running ParaView with a separate, connected pvserver?
If you have an NVIDIA card you may be able to use their EGL libs for offscreen rendering (i.e. no x-windows needed). See the blog post at https://blog.kitware.com/off-screen-rendering-through-the-native-platform-interface-egl/.
