Rendering artifacts occur when the below code is run with metal pipeline with uiScale=1.0 (or on external monitor)

Please note that it is not a bug in XOR mode implementation. It is found while working on XOR mode.

g2d.setXORMode(Color.LIGHT_GRAY);
            GradientPaint blueToRed = new GradientPaint(10, 600, Color.BLUE,
                    250, 700, Color.RED);
            g2d.setPaint(blueToRed);
            g2d.fill(new Rectangle2D.Double(10, texturePaintSectionY, 240, 100));
            GradientPaint blackToGray = new GradientPaint(10, 800, Color.BLACK,
                    250, 700, Color.LIGHT_GRAY);
            g2d.setPaint(blackToGray);
            g2d.fill(new Rectangle2D.Double(10, texturePaintSectionY + 100, 240, 100));

See output screenshot generated with OpenGL and Metal pipeline.

I have debugged a bit, it looks like - method MTLBlitLoops_SurfaceToSwBlit has a bug. I could not conclude what needs to be fixed.
