This is a known limitation of the engine. I don't consider it a bug and it is not something we intend to fix (at least not soon).

For the curious: When the screen is drawn we need to collect all the entities that will be drawn. The more entities there are the lower the performance is. If we collect all the entities in the world we get the perfect drawing. But that would be insanely slow. So we collect entities only from the visible area + small window around (to deal with special cases like wire drawing between poles that are both outside of the screen). Lights are handled separately (there is a larger radius for the collection outside of visible area). Anyway if the entity is outside of this rectangle it will not be drawn even though it might need to be (its visualization falls in the screen or so).
