Naturally generated light sources (fire, glowstone, torches etc.) sometimes do not emit light

I started a new world in 1.4 and entered the Nether. I noticed, that some Glowstone "piles"(dont know the correct word 😉) dont create lighteffects. The bug affected blocks had a grey layer an the texture. After hitting them(block update) all the Glowstones were lightsources and had the normal glowing texture

Also affected light sources:

  • torches in mineshafts

  • fire, lava in the nether

  • end rod in end city

Please attach screenshots.

Hitting them or destroying one of them?

I have seen this effect. The game engine does not apply the dynamic lighting to glowstone when the chunk is generated. Usually happens if I am generating new chunks quickly by flying or something. A block update does fix this 100% of the time by triggering the dynamic lighting to refresh.

Confirmed in 12w50b and included all other naturally generated light sources.

Can confirm for 1.12.2

1.13 Pre 5: Returning to a tiny island I had previously placed torches on and there's an area that shows a light level of 0 when a torch is very near (just across a chunk border). There's anther torch a few blocks farther away one level lower than the 0 light surface that's in the same chunk and it's not producing light in the area
