I'll look into it. I just installed Fedora 25 yesterday. It is not unusual for Fedora and other bleeding-edge distros to break things, because most commercial TurboVNC users are using RHEL or SLES or Ubuntu LTS. Thus the majority of users won't notice issues like this until they make it into the enterprise/long-term distros.
