This behavior is expected?
I’m not sure what you mean by that, I included the imports you mention. Although it should be noted that
import vtkmodules.vtkInteractionStyle
import vtkmodules.vtkRenderingOpenGL2
Are already part of the example code I linked in the OP. replacing with
from vtkmodules.vtkInteractionStyle import vtkInteractorStyleSwitch
import vtkmodules.vtkRenderingOpenGL2
makes no difference
I’m glad this topic is getting some discussion now that someone else has replicated the issue. I imagine it has something to do with macOS
