Future vs Fantasy Quake

Well, I found this bug many times but I always forget to take screenshots. But today, I took a screenshot and here you are, an odd texture:

This happens when 2 brushes with different textures overlap each other, creating this texture mixture effect.

Many texture errors like this can be found alot in Quake. You do not see them in wqpro though.
