DVB-subtitles missing RC4

Anybody else noticed that DVB-subtitles (transmitted as a separate stream) are not visible in latest Krypton Release Candidate? I checked also couple of latest nightlies and subtitles are still working in couple of days old build but not anymore one nightly back. Clearly Kodi recognizes the subtitle-stream as it can be seen as an option in Audio-OSD but it is never shown on-screen. Platform Windows x64.
