Copper ore lighting issue

copper ore emits light in 0 light levels, as you can see in the attachment, in 0 light levels there is a major texture/lighting issue with the stone around it and the stone texture on the ore seems off or as i saw it, it emits a small amount of light just like when brewing stands did before, and i did not make an example of the fact that ores emit light in the minecon videos for demonstrations.
