Hi, I'm operating a late 2013 27-inch iMac with 3.2 GHz Intel Core i5 processor. Currently running MacOS Mojave 10.14.6

Since installing the latest InDesign update (16.2.1) I've experienced various document preview issues:
- images that are contained within circular or other non straight-edged image boxes are not displaying at all.
- I get either a black box displaying or no box/frame at all. The frame is there because when I hit Select All I can see it but the image simply won't display at all, whatever the Appearance setting is on.
- However, if I create a JPEG or PDF from the document, the image appears in the PDF or JPEG OK.
- Also issues with items displaying properly (or at all) when moving between zoom-in/zoom-out settings.

After posting my experiences on an Adobe User forum I was advised to uncheck the GPU Preview option in InDesign Preferences panel and this has resolved the problems.
