See also [12000](https://discourse.vtk.org/t/invalid-shadow-shape-affected-by-the-aspect-ratio-of-the-window/12000).

I’m having similar artifacts. If I start recompile so that the render window is square, I get good shadows; and it survives resizing the window (although my window is not as well behaved as in the video above). But if the render window is _not_ square, I get cropped regions of illumination.
