HELP! weird stripes of lighter distortion on render result

the attached image should say it all

Please always attach your blend file to your post (including any textures). The screenshot shows nothing about your scene setup, materials and render settings etc.

some material i have under copyright and would not like to post, all i will say is that i am using NO RAY TRACING the classic halo stops on my spot light and 4 steps, when i change my camera angle significantly it works fiine, but it is important that i use this camera angle.

PS: it shows my halo settings, if i turn off halo it works fine, i have my halo settings circled, for a bigger image, go to
