I'm not sure if this was brought up yet, this thread is crazy long, but I was playing Switch Multiplayer with a LAN connection, I was hosting my friend on my farm and his screen had visual glitching where about only 80% of his switch's screen had proper lighting for the location/time of day. For example, at night, most of his screen would be the proper night lighting and color scheme but the remaining 20-ish% of his screen was lit as if it were day. This sort of thing also applied to dramatic lighting like inside the bus tunnel and mines. This was only happening to his Switch as a guest on my server. I did not experience this issue. Thanks!
