Massive Reflection Troble

Hi everyone, what can 3 reflection bugs be related to?

  1. In the reflections spot is shown where I look, in other places for some reason the shadow. How to make it so that in the reflections also looked like a shadow as in reality?
  2. Why can appear such strange white sticks at a high angle?
  3. Around the frames of glass for some reason at a distance appear strange white traces, they would remove …
    Lumen+Lumen, basic settings, only reflections hit by reflection, if you put the default, it will be the same, but will lose even more shadows. Glasses are one-sided, not Nanite (it has the same problems)
