If by disappearing triangle you mean what I think you mean (half of a texture disappearing depending on what angle you view it) then that is unrelated to the clipping error of the sign.
Yes, it's exactly that. I know it seems unrelated because the disappearing triangle happened with transparency and this one happens with signs on hollow walls, maybe just a coincidence that they started to happen at the same time.
