Duplicate of [vtk-8.1 has GPU memory leak? esp. on Linux. the related class is vtkXOpenGLRenderWindow](https://discourse.vtk.org/t/vtk-8-1-has-gpu-memory-leak-esp-on-linux-the-related-class-is-vtkxopenglrenderwindow/12879).

Please do not re-post the same question (or, if these are different, the details are not enough to tell that they are separate).
