Flickering lines appear on distant blocks when moving the player or camera

Summary:

Flickering lines appear on distant blocks on the world surface and in caves when moving the player or rotating the camera. The issue is most noticeable with Anti-Aliasing set to 2, but can still occur at higher levels in caves. These lines are also visible when the Night Vision effect is active, and changing the time of day does not affect their color.

On the surface, setting Anti-Aliasing to 8 or higher eliminates the lines. However, in caves, the lines remain visible but are much less noticeable.

Steps to Reproduce:

  1. Use the following seed: 1558083136.

  2. Fly upwards and face to the left.

  3. Set the Anti-Aliasing option to 2.

  4. Move the player or rotate the camera while looking into the distance.

  5. Teleport to the following coordinates: /tp 6229 -21 3645.

  6. Face the lava aquifer.

  7. Move the player or rotate the camera while looking into the distance inside the cave.

Observed Results:

Flickering lines appear on distant blocks when the player or camera moves. These lines are very noticeable and distracting.

Expected Results:

Distant blocks should render normally without flickering lines when the player or camera moves.

These lines are also visible on the surface and look much worse.
