[vtk-developers] VTKRenderWindowInteractor.py does not display correctly on retina display

[David Gobbi]

Hi Brian,

The retina code in VTK is still under development.  In the VTK master
branch, retina should work fine for pure C++ VTK apps, but it might not
work for python yet.  But feel free to try it if you want to be a guinea
pig.

The VTK 7.1.0 release doesn't support retina displays.
