Why do I get this strange view when switching to Wireframe Viewport Shading?

This is a screenshot of a cube in wireframe viewport shading:

Feel free to inspect the .blend file:
NoWireframe.blend (2.5 MB)

I had many objects in this file. Then I erased everything, then I added this new cube and the problem still persists.

Thanks guys,

You must have accidentally set a view clipping region.
Alt B will fix it (or view menu - view regions - clipping region)
