- Create sprite atlas with padding = 2 https://forum.unity.com/threads/artifacts-in-a-2d-pixel-art-scene.1427049/#post-8959284
- disable antialias
- use pixel snap shader material
- texture importer: point filter
- use unity pixel perfect camera package
- scale grid by small amount (0.999, 1.001)
- resolution issue? float camera pos
- Please try reducing the Max Texture Size to a lesser size ( 2048) and also try to have separate atlases for transparent and non-transparent sprites (non-transparent are the ones that entirely fills the texture with no transparent pixels in it). Also please ensure to have High-Quality compression for textures https://forum.unity.com/threads/sprites-have-hairline-artifacts-when-using-spriteatlas-and-mipmapping-how-to-fix.713501/#post-4774556

- In order to make your pixel perfect camera work properly all your sprites wide and height needs to be even. That thing cost me like 4 days. Without this aspect ratios 1:1 & 3:1 was very jittery. https://forum.unity.com/threads/the-pixel-perfect-advice-ive-never-seen-anywhere.1385490/
