Describe the issue

I am trying to use OffscreenRenderer with the render_to_image function to create snapshots from geometry.PointCloud objects. My code is running OK from python, but crashes the kernel when running from a jupyter environment.

It seems the error comes from the filament layer (SIGSEGV)

Thanks for your help!

Steps to reproduce the bug

import open3d as o3d

width, height = 512, 512
o3d.visualization.rendering.OffscreenRenderer(width, height)

Error message

Kernel crash.

Expected behavior

Running without any errors.
