White "tear" lines (artefacts) frequently appear around some animation

Hello every one. Here is the problem:white line (artefacts) often appears around animations, do you know how to deal with it? These artefacts are occasionally seen as small "tear" lines between each image cycle of the bam at certain zoom levels, I have tried toggling on/off the following graphical settings: Nearest Neighbor Scaling, Sprite Outlines and Highlight Selected Sprite, but it seems that they are not responsible for this issue.
