[Mac] Copying an image makes it blurry

[csa-smt]

Describe the bug
On MacOS, when using the constructor org.eclipse.swt.graphics.Image#Image(org.eclipse.swt.graphics.Device, org.eclipse.swt.graphics.Image, int), the new image is more blurry, and the base image too.
The base image and its copies become more and more blurry as we use the same constructor again.
The bug seems to be created when the base image was created from an ImageDescriptor.
The bug occurs with any flag passed as a parameter to create the new image.

To Reproduce

Edit IMAGE_PATH to put the path to your icon, by example you can download it:

import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

import java.io.File;
import java.net.MalformedURLException;

public final class HelloWorld {

    private static final String IMAGE_PATH = "/path/to/file_icon.png";

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


        final ImageDescriptor imageDescriptor = ImageDescriptor.createFromURL(new File(IMAGE_PATH).toURI().toURL());
        final Image baseImage = imageDescriptor.createImage();
        final int imageWidth = baseImage.getImageData().width;

        shell.addListener(SWT.Paint, event -> {
            int x = 0;
            for (int i = 0; i < 10; i++) {
                final Image copy = new Image(baseImage.getDevice(), baseImage, SWT.IMAGE_COPY);
                event.gc.drawImage(copy, x, 0);
                x += imageWidth + 10;
                event.gc.drawImage(baseImage, x, 0);
                x += imageWidth + 10;
                copy.dispose();
            }
        });

        shell.setSize(400, 300);
        shell.open();
        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
        baseImage.dispose();
        display.dispose();
    }
}

Expected behavior
The base image and its copies must not be blurry.

Screenshots

Environment:

1. Select the platform(s) on which the behavior is seen:

• • All OS
• • Windows
• • Linux
• • macOS

2. Additional OS info

Tried on : MacOS Sequoia, aarch64

3. JRE/JDK version

Tried on Eclipse Temurin 21.0.5

Workaround

Create a temporary image by passing the ImageData of the base image.

Replace...

final Image copy = new Image(baseImage.getDevice(), baseImage, SWT.IMAGE_COPY);

... with

final Image tmpImage = new Image(baseImage.getDevice(), baseImage.getImageData());
final Image copy = new Image(baseImage.getDevice(), tmpImage, SWT.IMAGE_COPY);
tmpImage.dispose();
