Description

Zooming UI at program start wents right but all buttons responds from wrong locations (as if the zoom/scale factor would still be the default 1.0).

This effect can be easily tested with ApachePivot org.apache.pivot.demos.text.TextPaneDemo
by adding ScaleDecorator & setScale before window.open(display) call like this:
....
final ScaleDecorator sd = new ScaleDecorator();
window.getDecorators().add( sd );
sd.setHorizontalAlignment( HorizontalAlignment.LEFT );
sd.setVerticalAlignment( VerticalAlignment.TOP );
sd.setScale( 2.0f );
sd.update();

window.open(display);
textPane.requestFocus();
}

The program UI will scale correctly the but buttons will react from wrong locations.

There is a issue report in the pivot-user mailing list archives: March 2015 with the same header as well with more information.
