Collaborative view only updating after mouse over

Hi all,

Vaadin 14. I need a “collaborative screen”, and it is working nicely, except …

The only issue is that 30% of the time it works immediately, but 70% of the time the “listening screen” does not update until it receives a “mouse over” (or similar) event.

I have posted a quick demonstration screen cast (audio very bad).

I know the server side of the “listening screen” always gets the message immediately, but it is not displayed until later.

Any thoughts / clues / suggestions would be most appreciated.
