The only trouble I found with 8.9.x and this is not acceptable is often minix hang with black screen when I stop a video.
got the same with a old panasonic plasma but if a use a more modern led panasonic tv (supporting 24hz) : no hang, everything works as it should be.
It's a kodi beta problem.
i will soon post a new release with update LE + kodi B3
maybe it will be solved...
