Issue description

Teleporter frame blocks have non-smooth lighting when lighted up by any nearby light source. This is still a problem even if you light up each teleporter frame block with the same amount of light from the same direction, or place, say, a torch on each block.

This is an issue both with and without shaders, but it’s more noticeable with shaders enabled.

Shaders on

Steps to reproduce

1. Place teleporter frame blocks.
2. Light them up with a source of lighting—e.g., a torch.
