Hi Hans-Peter, A freezing UI is definitely a no-go so I am interested in a reproduction path for this so we can avoid this. The Kafka transforms have received some love and are being used in projects so I'm sure we will figure it out. As getting all the information via email might be a painful process, feel free to reach out to me on hansva[at]apache.org with your timezone so we can plan a short call to go over your problem.
