[vtkusers] VTK7 OpenGL2 Depth Problem

[Thales Luis Rodrigues Sabino]

I'll assume you're using PCL Visualization Module.
Have you tried opening the point clouds in a non pcl application?

I'm using VTK6.3.0 with OpenGL2 backend building my custom application and
the rendering is fine.
I'll try VTK7 soon though.
