[vtkusers] vtkCaptionActor2D text appears chopped

[Roberto Garrido]

Hi,

 

We have added a vtkCaptionActor2D to our scene, but the text appears
chopped, and we don't know why.

A simple and compilable example that shows the output text chopped is sent
attached.  Also, an screenshot at the bottom.

Could anyone try to reproduce the error?

 

 

Thanks in advance.

My best,

Robert.
