Grasshopper - issue bounding box

Hi there!.

The problem seems to be very stupid. The bounding box doesn’t behave as expected with this geometry: there are 4 gaps there. What can be the problem? Graphicard card issue?

Please share your Grasshopper definition with the relevant geometry internalised.

I’m posting the gh file.

This works fine in Rhino 9 after converting the extrusion into a brep.

I don’t see any benefits in extrusions.
