The model started with a plan imported from CAD and was over 400 meters from the axes origin. I moved it to the origin, and the display issue is gone.
This definitely an issue. Not sure where it comes from but OpenGL gets confused.

I tried temporarily moving the axes to the model, but the display issue recurred.
The axes don't determine the location of the origin. The origin is a fixed point in the model space. By default the axes are placed at the origin.

So, for now, I'm marking its original location with a few lines, and even though there's now a little geometry in the distance, the model is displaying well.
Keep an eye on that, though. That geometry might cause you issues, particularly with Zoom Extents. My inclination would be to identify the coordinates of that distant point and write them down for later reference. YOu can always move the model back to that point later if you must.
