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
