In certain cases that are hard to reproduce:

scene with: comboboxes, jfxtras radials, tableviews, and Timer with async web service call.

on Windows system the system process at kernel level gets over 50% of cpu ussage and hangs the javafx app, is more noticeable on the combobox that gets laggy and frozen, all the app becomes frozen and have to kill all the associated process.

This happens in browser and in desktop

I will try to get some user case scenario although is hard due to the app only freezes when we are at a window that has a lot of heavy work making 2 WS calls every 2 seconds with Timer, and updating all components on the windows.

On Mac Version is not that visible but processor gets very high and start downgrading the system performance.
