Thank you very much for your explanation and confirmation.

To my observations, Without -fix_xub_duration Vlc shows every subtitle, but no subtitle will disappear again. So after a short time you have quite a mess of them.
Adding -fix_sub_duration as input file option seems to provide a sensible duration for every subtitle to be shown. So vlc shows only one subtitle after the other.
