Broken UI

Running the following SWT sample results in a a broken UI (as seen in the attachment).

package t;

import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

public class Reproducer {
	
	public static void main(String[] args) {
		Display d = new Display();
		
		Shell splash = new Shell(d);
		splash.setBackgroundImage(new Image(d, Reproducer.class.getResourceAsStream("splash.bmp")));
		splash.setSize(455, 295);
		
		splash.setLayout(new FillLayout());
		splash.setBackgroundMode(SWT.INHERIT_DEFAULT);
		
		Composite fCompositeLogin = new Composite(splash, SWT.BORDER);
		fCompositeLogin.setLayout(new GridLayout(1, false));
		
		Composite spanner = new Composite(fCompositeLogin, SWT.NONE);
		GridData data = new GridData(SWT.FILL, SWT.FILL, true, true);
		spanner.setLayoutData(data);

		Label label = new Label(fCompositeLogin, SWT.NONE);
		label.setText("Hello World:");
		data = new GridData();
		label.setLayoutData(data);		
		
		Text text = new Text(fCompositeLogin, SWT.BORDER); // Comment to see it working 
		Button b = new Button(fCompositeLogin, SWT.PUSH); 

		splash.layout(true);
		splash.open();
		
		while( ! splash.isDisposed() ) {
			if( ! d.readAndDispatch() ) {
				d.sleep();
			}
		}
		
	}
}

It looks like this is somehow caused by the Text-Widget if you comment that code you'll see all looks good. This is on BigSur I didn't yet test it on pre BigSur-Releases.

BTW: This is trimmed down version from "Interactive Splash"-Template.
