The problem arose after the engine change. If the anti aliasing is above 1x black streaks appear in flat areas that are a little distant from the player and they are wobbling as we walk the map.

This problem is most noticeable in desert, plain, and sea biomes, and increase a lot when we use 128x textures packs. This did not happen before this update and anti aliasing 4x worked fine, now the game is very jagged even with anti aliasing at 8x, and still has this problem mentioned above
