Description

Hi, I used render_to_image code to run on Linux, macos and windows systems respectively, why is the result different?

on linux:
python 3.6
open3d 0.14.1
Ubuntu 20.04.3
![linux](https://user-images.githubusercontent.com/75186221/145384009-5467feb3-5d37-407b-a5f6-dc74445418d4.png)

on windows:
python 3.6
open3d 0.14.1
windows 10
![win](https://user-images.githubusercontent.com/75186221/145384080-25535a70-ce3d-4641-9a4d-fb89c234926c.png)

on MacOS:
python 3.6
open3d 0.14.1
macOS Catalina 10.15.7
![mac](https://user-images.githubusercontent.com/75186221/145384180-479494db-8309-418e-98a0-3ca34c1c1950.png)

The results generated on the mac are completely invisible. Why?

The results generated on Linux have very unnatural light reflections. You can see that the reflected light in the upper left of the black object is white, which makes no sense. But the results generated on windows are more reasonable. Also the image framing is different between the two.

What could be the reason for these differences?
