gauge's title resize abnormal

[dongwenting]

when I resize the window, gauge's title become small.

but I can't reappear this in your MultiGaugeDemo, it only happens in my application.

Can you give some suggest to find the reason?

Please close the issue. I don't know how to do it and I find the reason.
I add font-family to the root.

scene.getStylesheets().add("style.css");
style.css:
.root{
-fx-font-family: 'Microsoft YaHei';
}
