Thanks for the report. You have successfully re-discovered what I call the "Peter Maxx" bug. So far it remains illusive. I've only had it happen once and that was on my previous computer. It won't duplicate for me with your models.

This one is my favorite:

I like this one as well:

This bug has showed up very infrequently over the last 8 or 10 versions of Cura. It doesn't affect the gcode, but it looks really bizarre when it happens. The Cura team will take a look. I'm going to mark this as a duplicate of #13417 and others. Don't hold your breath because this one has been tough to find.

I was initially reproducing it consistently even with app restarts, but now seems to stop happening after a bit even without restarting the app

That's what has happened before. The bug appears and disappears apparently at random which makes chasing it down near impossible. It's like trying to find an intermittent electrical fault. Something seems to be going on between Cura and the video system/OpenGL driver but what I don't know about video systems and OpenGL fills libraries.
