Processing IDE与Eclipse运行效果差异问题

问题现象

我编写了完全相同的Processing代码，分别在Processing 4.3 IDE和使用core.jar包的Eclipse中运行。两者均生成白色背景上带圆角的矩形，但存在两个明显差异：

Eclipse中矩形的画质远差于Processing IDE
尽管设置了相同的窗口尺寸，Eclipse中的窗口也更大

环境信息

Windows版本：10.0.19045 Build 19045
Eclipse版本：2023-03 (4.27.0)

Processing 4.3 IDE中的代码

final static int screen_width = 1400;
final static int screen_height = 600;
final static int button_width = 500;
final static int button_height = 200;
final static int border_width = 8;

PVector button_startingpoint;


public void settings() {
  size(screen_width, screen_height);
}

public void setup() {
  frameRate(60);
  button_startingpoint = new PVector((screen_width / 2) - (button_width / 2), (screen_height / 2) - (button_height / 2));
}

public void draw() {
  background(255);
  fill(255, 255, 255);
  strokeWeight(border_width);
  rect(button_startingpoint.x, button_startingpoint.y, button_width, button_height, 24);
}

Eclipse中的代码

package main;

import processing.core.PApplet;
import processing.core.PVector;

public class Startup extends PApplet {
    final static int screen_width = 1400;
    final static int screen_height = 600;
    final static int button_width = 500;
    final static int button_height = 200;
    final static int border_width = 8;

    PVector button_startingpoint;

    public static void main(String[] args) {
        PApplet.main("main.Startup");
    }

    public void settings() {
        size(screen_width, screen_height);
    }

    public void setup() {
        frameRate(60);
        button_startingpoint = new PVector((screen_width / 2) - (button_width / 2), (screen_height / 2) - (button_height / 2));
    }

    public void draw() {
        background(255);
        fill(255, 255, 255);
        strokeWeight(border_width);
        rect(button_startingpoint.x, button_startingpoint.y, button_width, button_height, 24);
    }
}
