When I fired an arrow (Spectral) at an entity and looked at it my game window content blacked out. When I looked away from it I could see everything, but when I had that entity in my FOV again, my window turned black...
That was the case until the glowing effect on the entity ended.
P.S.
When I fire Spectral arrows at blocks I can see their texture and everything looked normal.
