Apparently, if you standing close enough (happens in original portal 2 as well) you can see a seam on the left or right side where fizzler_l or fizzler_r texture ends.

This is because the texture filtering wraps around, so it reads the other edge of the left/right texture which is brighter. It could be fixed by tweaking the 4 pixels on the sides.
