Block like Stone, Cobblestone, Dirt renders without light in any drawers, but items like Rails, flowers, DE Cores doesnt have this problem.

Modpack: FTB Presents Stoneblock 2

No errors in log.

Getting the same issue in Engimatica 2.

not sure why this was closed...I still get this problem. Its only doing it for 'blocks' not items.

Rotten flesh, coal, ingots, diamonds are fine.
Cobblestone, dirt, ores, wooden planks/logs however are affected.

Not sure whats causing it, going away sometimes or looking at it from a different angle sometimes fixes it, or causes it to flicker.

1.12, optifine.
