JavaFX graphic performance slow on Mac? Clock app

[Kevin Rushforth]

You will need to build OpenJFX from source to get the windows 
implementation of the ES2 pipeline. We strip it out of jfxrt.jar before 
shipping it.

I created a little clock app which uses between 25% and 80% cpu usage. But what’s the reason for? I though JavaFX rendering pipeline works on the graphic device? So why there is such a traffic on the CPU?
