Hi, after several problems solved previously and during 3D Forest compiling, i managed to compile it on Ubuntu 22.04. But when i start the executable, sometimes it crashes with the message "Segmentation fault (core dump)" and sometimes starts normally.
I used gdb and the backtrace output of segmentation fault is this:

I'm not sure if the problem that causes the segmentation fault is generated whether by pcl visualizer or by vtkXRenderWindowInteractor.

EDIT Solved this issue, see #35.
