When I apply a transparency to a raster image (ie. an airphoto) and export my layout in ArcGIS Pro to PDF, strange lines appear in the image (almost like the software is tiling it). If I remove the transparency, then the export is fine. I have tried adjusting the DPI during the export and printing directly to PDF, with no luck.
Has anyone else had this issue... and if so is there a fix? I am using ArcGIS Pro 2.0.1.
