Huge street fill visual glitch

Hi,

I'm trying to figure out why I get this behaviour with a really big fill that represents the streets of a city. Yes, it's one single huge fill.

If I zoom out, I get this visual glitch that stems somehow from this huge fill.

If I zoom in close enough, the visual glitch goes away.

I can fix it by exploding everything and retaining just the outlines, but I would have liked to retain the ability to change the color of this huge fill if need be.

Some relevant things, the fill is a simple drafting fill, it has a simple foreground fill type and an solid line outline type.

There's no fill origin shenanigans.

Exploding this huge fill will still retain this artefact from the resulting elements (fills + polylines).

I've copied this fill in a clean AC28 file so anyone can check it out.

If anyone else encountered this before maybe you could help me answer my questions: is this a bug? is this fixable in any way? is it just a limitation of the fill tool? is it something related to the 2D engine? Maybe something related to how this fill was imported in Archicad?

Operating system used: Windows 10
