vtkMath::Jacobi: Error extracting eigenfunctions using vtkAbstractPicker

Hi again,
I’m hitting a strange problem using vtkAbstractPicker. Specifically, when I initially load my render window and try to use the Pick method of a vtkAbstractPicker to get the 3D coordinates corresponding to a mouse click, I get this exception:

vtkMath::Jacobi: Error extracting eigenfunctions

However, the error only happens for the first click. Moreover, if I remove the renderers attached to the render window and replace them with new ones, I don’t get the error. The error seems to be specific to the first click in the render window.

Any ideas as to what’s going wrong? I get the error in both VTK 8.1 and 8.2.

I figured out the problem. I was trying to plot items outside of the limits of the image viewer. Oops.
