[platform-swt-dev] Weird shell size on Windows

[Thomas Singer <ts-swt@xxxxxxxxxxx>]

I'm using following tiny snippet to show a shell with a certain size on 
my Windows 10 machine with 4K-monitor (200% zoom):

import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;

public class WindowSize {

	public static void main(String[] args) {
		final Display display = new Display();

		final Shell shell = new Shell(display);
		shell.addListener(SWT.Resize, new Listener() {
			@Override
			public void handleEvent(Event event) {
				System.out.println(shell.getSize());
			}
		});
		shell.setSize(400, 300);

		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}

		display.dispose();
	}
}

As it is printed on console, the size is equal to the one specified. 
While debugging it is obvious that the file is scaled to double-size, so 
actually Control.setBoundsInPixels() is invoked with 800x600 as 
argument. So far, so understandable, but when I take a screenshot with 
Alt+Print and paste it into a graphic application, e.g. IrfanView, the 
size 778x589 is displayed. The same occurs if I use, e.g. GreenShot to 
take the screenshot and view its size. This somehow makes me wonder 
where the remaining 22x11 pixels have gone.
