Heads and skulls on a wall cause z-fighting when viewed in Spectator mode or at certain angles. This is not the case for Dragon Heads.
The bug is caused by the fix of
- Place a head or skull on a wall.
- If a wall head is placed, switch to Spectator mode to view it from the inside.
→ The head shows z-fighting from the side.
- If a wall skull is placed, view it from below.
→ The skull shows z-fighting from the side.
