At least one of these is a bug but I also took screenshots of a weird collision box around a boulder and strange lighting on hands.
The first in a monster spawning over water when I think he should be over on the peninsula.
This picture shows an abnormally large collision box around a boulder next to a cemetary near the central city in the desert.
This last picture shows a lighting or texture bug on my hand while in the cave past the burning forest. My graphics are on normal for this.
