PhotoPlus X6: fantom grain/noise

Hi, having tried out the new PhotoPlus x6, I find that the view of the picture you are editing appears grainy, This is just how Photoplus appears to be displaying the pic, because if you "preview in browser" or save file and look at it in another application, say windows picture viewer, the picture is fine, no grain.
