Artifacts between orthoimage tiles at certain scales

Hi everyone,

I've encountered an issue displaying orthoimages in ArcGIS Pro (I'm on version 3.2.2). There are artifacts appearing on the edges between some of the raster tiles, but only at certain scales. E.g. at scale 1:3000 they are displayed seamlessly, at 1:5000 artifacts appear, which can be seen on the following screenshot. (My map background is black, that's why it is a black line. It seems like the background flashes through.)

This behavior occurs both when I load the images directly in ArcGIS Pro and when I add them to a mosaic dataset. Interestingly, when I load the same data in QGIS, the display works seamlessly without any artifacts.

The coordinate system of all the images is the same as the map coordinate system.

Is there a setting or configuration that can prevent this behavior in ArcGIS Pro?  I'd appreciate any solutions.

Thank you!

I was able to solve the problem. I found out that the rasterfiles have internal overviews, which were causing problems in ArcGIS. As a solution, I created pyramids (.ovr files) for each rasterfile. After that no more artifacts appeard.
