Is it a bug?

[efferto]

Hi @grahamrow, thanks in advance for the useful visualization software.
I'm experiencing something strange in the laster version, I have also checked building from the master branch and I get the same results.
With version 2.1.3.3 I was able to see the following two square correctly with empty space in between. Se the screenshot.

With the latest version (master or 2.2a2), instead of the empty space, green cubes, vectors or cones show up. See attachment 1 and attachment 2.

Could it be a bug?
