Bug or setting

[chasseur de dragon]

Hi,

on archicad 22 + corona render, there is a moment where I end up having a bug.

there always appears a line just above the ground level.
I do not understand where it comes from?

Do you have an idea where this may come from?

Hi, is this still a valid issue? I'm not able to reproduce it on my project.
If possible, please send me your project so I can investigate it?
