Random view switching and no response

Over the past few days I have experienced strange behaviour in Lovelace - UI on Hassio 0.85.1.

In Safari, when I first load the front-end and click on a view there is no response. I then click on any other view and it work from then on.

Furthermore, Lovelace is randomly switching to the first view without any input.

I am using the following custom cards:
state-switch
slider-entity-row

Any ideas would be welcome.

Thank you.
