I make a 2d platform game in Unity3d 5.3.6. The level is built from sprites 32 * 32 pixels, respectively, 1 unit per 1 unit. Scale 1 * 1 * 1. Sprites (game objects with SpriteRender) are placed on coordinates equal to integers. Anti-aliasing in the engine settings is disabled. But from time to time they appear in the game window and in SceneView there are such highlights between the tiles: 
I tried to include in the standard sprite pixel snap shader - it did not help.
It became even worse - between the animated time-lapse sprite animation game objects such a gap began to appear constantly. I didn’t find free shaders in the network to solve this problem, and I almost don’t know how to write shaders.
