Here's the effect using 0.65x resolution. Note that the cutoff point for the glowing effect is the same as the cutoff point for the illager model being visible. The area where the glowing effect shows up appears to be around two fifths of the width of the entire screen. It grows as the resolution multiplier is increased, lining up with the models at 1.00x resolution, then scaling outwards at values over 1.00x.

still an issue over two years later
