ArcGIS Pro tif export with line on the edge

[JillSlater3]

I am exporting tiffs from ArcGIS Pro 2.4, and I see a fading of the pixel colors on the edge of the exported tif. I have a feeling it has something to do with the pixel size and page size that I am using (96dpi, 100cmx100cm page size), because 100cm doesn't fit nicely into 96dpi. I made sure to remove all of the borders and shadows on the map frame. Here is an image of the edge of a tiff export, showing the different colors of the pixels at the right side edge:

We are using the same page size and resolution settings as we use for the same maps in ArcMap, and we do not get this line on the edge from those exports. My question is, what is different in ArcGIS Pro that causes this to happen, and is there something else I can do to prevent it?

That is odd. Unfortunately the only suggestion to prevent it would be to not use Pro to do it.

I would assume your using the same computer that has the same rendering power (this question is a stretch)
