[vtk-developers] issue with interactor in viewport

I currently have two viewports (a left and right viewport) but the
interactorstlye for the right viewport isn't working correctly. It
should display the labels of the different slices of the pie chart on
hover, but the hovering only works in the left viewport. It looks like
the "position" of the interactor is off. I attached a screenshot of this
issue (this is when my mouse is hovering over the left viewport). 

# Set up a 2D scene, add a chart to it 

view = vtk.vtkContextView() 

chart = vtk.vtkChartPie() 

# Add renderer to render window and set viewport 



view.GetRenderer().SetViewport(viewport2[0], viewport2[1], viewport2[2],

# Allow interactive piechart 

style = vtk.vtkContextInteractorStyle()
