so at least it’s not just me.
Hopefully the devs will pick up on this.
In my case my TV Model is a Sony Bravia KD55XD8005
Edit:
AS the interface was so unusable, I have now uninstalled that one and installed/sideloaded the previous beta 7.26.0.14321-beta and the user interface has returned to normal.
So it does seem be an issue with 7.26.0.14345
