Images and Elements Disappearing and Reappearing in InDesign

Macbook Pro (Retina, 15-inch, Late 2013)

macOS Mojave, Version 10.14.6

InDeisgn Version 16.4

NVIDIA GeForce GT 750M 2 GB

Intel Iris Pro 1536 MB

GPU Driver Version: 355.11.10.50.10.103

NVIDIA/CUDA Driver Version: 418.163

Please see screen shots...

I reduced this rough design to a few elements to show what's happening.

Screenshot 1: What it should look like.

City is a jpg with a PS clipping path and Indeisgn drop shadow.

Text is converted to paths.

Icon is a vector/compound path.

I exported this screenshot as a JPG from Indesign. Looks correct when you export as a PDF as well.

Screenshot 2:

What it looks like at 25% in InDesign.

Now, randomly, if I zoom in and out, the text may show up, but the icon never does.

When I go to Slug View, the text disappears. Then (possibly) reappears in Normal View.

The icon is on the top layer. The city is on the next layer. The text is on a layer below that.

Screenshot 3:

What happens when I delete the city.

Everything else reappears.

I have had even more bizarre display anomolies, and one where I had to bassically rebuild a spread that was designed in 2019 to make a few minor changes.

Hopefully this is enough info to go on. Any help would be appreciated. Thanks, Pete
