GLB glass-like panel weird artifacts


I created this building In Blender and exported it in glb, then used it like this:

const { scene } = useGLTF(url);
	return <primitive {...props} object={scene} scale={scale} />;

But I am getting these weird shapes, and I thought the issue was with the vertices in my building so I made a new plane from scratch and just applied the material to it, but it’s still rendering those shapes.

My shader is just a Principal BSDF in Blender with transmission =1, IOR=1.5, and Alpha 0.9

Anyone know what’s causing this?
Thank you for any help.

Here’s the glb files:
plane.glb (1.4 KB)
warehouse.glb (10.2 KB)

when I drag it on here: https://gltf-viewer.donmccurdy.com/

i see:

Looks like some of the metal frame geometry is intersecting with the transparent plane a bit.. but other than that.. I don’t see those artifacts?
