 Yes, for a human it's easy to see that this position is a clear cut draw
 and nothing else. Black's rook and king are tied up in defence of the f-pawn.
 If the h-pawn moves it gets eaten. Of course the black bishop can move around
 and have a look at the views, but the programs really look stupid with these
 evaluations. And furthermore, white can force the draw by chopping off the
 wood on f5 and put the king on h1...
