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 www.moltenurumedia.com/101010102.png
