Unfortunately these arrows are a bit of of a nightmare to get right. Or not really the arrows themselves but layered objects outside the terminal. I don’t want to go into the detail here but it is briefly because we use a mix of different techniques such as different shaders, materials, sprite sorting layers and position Z-value. It is basically a must to get the maximum rendering performance (especially during nighttime). It is a matter of fixing the layering in one place only to screw it up somewhere else. We will take a look again!
