@OmegaThree These aren't raw Stockfish logs so it's hard to tell what the problem is. Is it that it went from M43, M42, M45, M42 on depths 55-58? From my understanding this is expected behavior. Neither cp or mate are expected to go in one direction as depth increases. I know it seems like mate should be a stronger guarantee but that's not really how it works. "Best information based on what we've searched so far" is probably a better description.

You're missing the seldepth here so it's hard to tell what happened but from eyeballing it you can see its choice for black's best response to 21.Kc2 bounces around between Kxc5, Kb4, Kd5.

@judwhite The logs are from Stockfish 17. This is another mate with a more pronounced effect.

There was a similar problem last year which got fixed and thats why I raised this issue.

There was a similar problem last year which got fixed and thats why I raised this issue.

But what is the problem?

there is indeed no guarantee that the mate distance found only improves with increasing depth, i.e. that information is not stored and retrieved, each depth searches the position using little information from the past, except the transposition table. So, a large transposition table should help to avoid this problem. We now track quite carefully the mate finding ability of SF, see https://github.com/vondele/matetrack there is no recent unsolved issue with mate finding.
