Question on vtkRenderWindowInteractor

Support
1

Hello,

I was exploring examples of vtkRenderWindowInteractor when I noticed a strange behavior. When I press the key 3 in the render window, the entire window turns pink. I am not sure whether this is intentional or a bug.?

Can anyone please explain why this happens and how I can disable it?

It is not a bug, key 3 invokes stereo mode. If you want handle the event please see KeypressEvents also see KeypressObserver.
