[1.12.2] paint/block z-fighting + stamp crash

[toonlinky]

forge: 14.23.5.2860
i dont know if the mod creator is active anymore, but i just really miss using this mod... :/

previously, the paints i did on blocks would look normal, but recently, paintings now collide with blocks and that causes z-fighting when i move away from it...
right-clicking on a paint with stamp just outright crashes the game for no reason

Are you using Optifine? If yes then this is most likely the cause. Otherwise, can you give me a list of all the mods you use?

i have just right now noticed this reply, darn it! here are all of my mods currently activated, and yes, i do use optifine, but i use it for the optimization purposes, although prior it worked with optifine, it also touches other mods for odd reasons

i know this is late and im really sorry ;-;

if you can respond now, also sorry for necropost (i just dont know if making a new issue is worth it in this case), optifine was the problem with z-fighting, but the crash with stamp persists and i dont know which mod (mod list above) does the thing that makes it crash (or it has problems in the code itself)

upon trying to copy a drawing with it however, outputs with a crash error: https://pastebin.com/mc3WxD9D
if i need to make a new issue then alert me please
