I really don´t know what´s heppening. Simply appeared these lines between the blocks from one moment to another. I've tried seen videos on youtube that was talking about that proprably the problem is with the video card, so I was trying and trying fix, but nothing happend. So I decided open in another version of minecraft (1.14.4) and put the mipmap levels in zero, for my surprise solved the problem! So I opened again the newest version of Minecraft and made the same procedure, but nothing happend again, the bug are there like before. Someone can help me?

OBS.: Not just these configs, but like the others ones available in the game.
However, not solved the problem.
