I am combining several raster images into a single image via the mosaic to new raster tool. It has worked great on other attempts in the project except there is one image that has white gaps when zoomed out (zoomed in they disappear). None of the others have this problem. I made sure to input all the correct perimeters for the tool.
32 bit float is the pixel type (original source rasters)
I am not sure if this is just a display bug or if there is some other underlying issue?
