Can anyone help me to understand the reason of this problem? Or, at least, to find the way to detect configurations that affected by this issue.

An idle speculation, maybe your shader writes alpha information in both cases, in the first case I don't know what happens with the alpha value, a long shot could be that the bits are interpreted as Red in the next pixel.
