Sprites with Mipmaps Vibration Effect on Animations Problem

I have sprite sheets, and simple animations for them. The texture type is Advanced Texture, and I enable mipmaps. I must enable mipmaps, because the details of the sprites significantly reduce. How can I fix this problem without disabling mipmaps? The sprites are building sprites, so they are stable and these vibrations can distract the eye easily. The animations are simple flag animations for example.
