The person who hears your concern should also hear what a workable improvement looks like.

A concern delivered on its own leaves the other person holding a problem and guessing at the shape of a solution. They often guess wrong, fix the wrong part, and then both of you are frustrated. Saying what better would look like is not softening the complaint; it makes the complaint usable.

The next time you raise something, add one sentence describing the version you could live with. Keep it modest enough to be possible. If you cannot picture that version yet, say so plainly and ask for their help finding it.
