--- Comment #4 from Eric Pouech  ---
submitted https://gitlab.winehq.org/wine/wine/-/merge_requests/5462 that should
take care of the buffering with 4096 bytes of stderr.

Note: letting stderr be always unbuffered (esp. when redirected to a file) is
only supported by Windows on ucrtbase, and in recent versions of it (win7/8 and
early Win10) let the buffering be in place.
