System Information
Operating system: windows 10
Graphics card: nvidia rtx 3090

Blender Version
Worked: N/A

Short description of error
following tracking and introduction of a 3D element, a wall positioned so that the 3D object passes behind an element of the video, therefore partially hiding the 3D object: during rendering with cycle, this is normal.

Then the freestyle application covers the 3D shape well, but the application does not take into account the part hidden by the wall and draws on it.

The result in the attached image, to the right of the image, the black lines on the yellow post.

Exact steps for others to reproduce the error

Thanks for reporting this issue, @Vince-3D.

To further investigate the problem, could you please provide a simplified .blend file that demonstrates the issue?

If this issue is a result of an automatic motion-tracking compositing of the scene, it's possible that the problem lies in the compositing setup (not in the freestyle). In that case, it would be helpful if you could provide more information about how the scene is composed and any relevant compositing nodes used.

ok, attached render and test .blend file.
Freestyle never takes into account the elements that hide the object.

I can confirm the issue you are experiencing. However, I noticed that you mentioned it worked on version 4.0.2. Could you please clarify if the issue only occurs on the latest version, 4.1?
