When that happens you have to move/adjust things to make it look right. The bigger/higher resolution the map and effects the more problems that pop up.
If you're not familiar with it, I recommend looking into the EXPORTSETMPPP command ( as described at http://rpgmaps.profantasy.com/?p=4292 ) for a way to reduce the likelihood of running into problems with banding and lights in CC3+.
