ZED-pcl and fusedpointcloud display


I am trying to use the zed-pcl sample code to display a 3D point cloud with PCL and also display the fusedpointcloud of this example.
However, these 2 displays don’t seem to work well together. I get a ZED_Point_Cloud_Mapping.exe: 0xC0000005: Access violation reading location 0x0000000000000000 everytime the GLViewer calls glutMainLoopEvent().

How could I make the 2 displays work together at the same time?

It should be easier to use this PointCloud class for your display purposes instead of the PCL display.

Thank you! Could you please provide some tips how to have multiple display windows running parallel?
