Image and text have grey overlay

Ignition 7.8.2. (I know. It’s time to upgrade.)

In developer it looks like this when run or stopped:

In Launch | Project | Windowed | Published it looks like this:

This also happens to a text area box on the same page. All other pages have charts or tables on them and don’t suffer this problem.

Any ideas why there is a grey overlay in published mode?

Many thanks.

Is the product flow diagram shown in a single image component?

I’d check the bindings to be sure there’s nothing relying on a client tag for changing the overlay color.
