Maybe @sp614x can tell us what's wrong now?
Yeah I decided to turn off all animation of doors because not all doors in my modpack have this implemented. However I made you screenshots of the light issue. First...
yeah. it is all black granite. And I thought the inner was too dark because you cannot see which block it is. But this might not be an issue. Secret...
The block underneath the door? yes.
It seems that it only happen if a block is placed above the door.  
OptiFine 1.12.2 HD U C7
Chisel - MC1.12-0.1.1.24 CTM - MC1.12-0.2.3.9 without Optifine 
I will check this.
Could you give me your modlist? I will check for same mods.
As you all can see, I have 940M in the screenshots, I will check if it happens with GTX 650 now.
