there is an issue of what you describe in Coreldraw espcially with x3 it has to do with how the corel render engine works. I know that if I zoom in out really fast it will create artifacts (on edges) that will export with the images in these file types
1. jpg, pdfs
I had a project a few years back it was collage of imagess and exported to pdf and never saw the error until after print...lucky for me the image was very busy so not noticeable to the untrained eye because it looks like it was done on purpose it was not!!
X4 seemed to resolve it but it had happened a couple of times
x5 this time I had white line on edges of images created in PPX5 imported into CDRX5 and zoom in out the lines would appear then disappear but the lines always exported when publishing to jpg ot pdf
THIS IS NOT AN AA PROBLEM. the line are sold edge on the lower left and bottom
only work around is to open in PP and clean up the edges
