Block edges remain undefined even with the Optifine

What are the effects of this in vanilla?

What even is this referring to?
Please follow the mojira guidelines, describe current behavior, expected behavior, steps to reproduce, clear description of the bug, etc.

Sorry for not specifying the problem well. A few weeks ago, I reported the MC-267594 issue and fixed it. But I noticed that the edges of the blocks remain undefined creating an effect that is not nice to look at

From a distance, the blocks are pixelated

The image attached shows the block outline when highlighted/aimed at, not that issue. Additionally, that issue is not fixed, that report is resolved as duplicate; the parent report is still open.

From a distance, the blocks are squared. creating an effect in vanilla that is not so nice to look at. The grass from a distance seems to move, moving me the edges of the blocks change

That's just resolution limitations. If you zoom in far enough on any image, you'll get that result. It's just more visible due to the contrast of the green short grass and brown dirt of grass blocks or blue sky.

(Sorry for the downtime.) Since I fixed the --1073740791 error I've run into a problem. If you look closely at the edge of the blocks it is (serrated),That's why when you move, the edges of the blocks move especially in the grass block.I don't know if it's because of the wrong driver or a wrong driver setting.
