I think you have the right idea for improving the behavior here. It should skip setting wShowWindow if startupinfo already has the flag STARTF_USESHOWWINDOW. For example: if shell: comspec = os.environ.get("COMSPEC", "cmd.exe") args = '{} /c "{}"'.format (comspec, args) if not startupinfo.dwFlags & _winapi.STARTF_USESHOWWINDOW: startupinfo.dwFlags |= _winapi.STARTF_USESHOWWINDOW startupinfo.wShowWindow = _winapi.SW_HIDE ---------- components: +Library (Lib) nosy: +eryksun stage: -> needs patch type: -> enhancement versions: -Python 3.5, Python 3.6, Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40851> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
