Rpi, Spotify plug in kills touch screen

I have a Rpi 2 with the official 7" touch screen which works perfectly with Volumio. That is until you install the Spotify plugin at which point the mouse appears on screen and will move for a few seconds (I think until the browser opens) and then touch inputs no longer register.

You can still operate the system via a web browser on another device and ssh works too.

Has anyone else found this and is there a fix?
