But this artifact disappears only when I change the matrix or change bitrate. But with this bitrate and output size byte to byte the only decision is to change matrix, but if you think that your matrix is perfect that's nothing to discuss. Besides I've already reinstalled every codec and the result is the same. My friends told me that they saw such artifact when they had compared the matrices (eqmv3hr with others).

From your pictures, I can just see that the problem _might_ indeed be related to custom quantization.
