I have reconfirmed this. > The bad case does look like a Gwenview bug, > but KDE bugs tend to disappear into the ocean, if reported. In fact, as I had forgotten (grimace), I did submit a bug previously : KDE Bug 420357 back in April 2020, to which no-one has yet responded.

I managed to do that & now have images which cb seen via Gwenview. > Any further suggestions re causes of the bad case are welcome.
