openGL GLSL undisired stacks of lines when indirect accessing texture

Dear aLL:

 

  I am using an ATI card for indirect texture accessing on color index using GLSL. While accumulating texel color (with opacity) on the ray path, I found There are two straight line along two side vertically and Below the textures on the polygon plane spanned by the texture. The slice number of those straight lines varies with the number of sampling texture along the ray path.

 

  I did not have any idea about the cure, does anyone has any good idea?
