Java-LWJGL-OS X Retina支持

Question

I searched so long for a solution to run a simple LWJGL application on my MacBook Pro with Retina display. The problem is that the Retina display is flickering. But I just found uninformative hints.

Do you know any code solution to handle this? For example changing the viewport or something?

What have I to add to the following code?

import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.Display;
import org.lwjgl.opengl.DisplayMode;
import org.lwjgl.opengl.GL11;

public class MainDisplay {
    final int DISPLAY_WIDTH = 640;
    final int DISPLAY_HEIGHT = 480;

    public void start() {
        try {
            Display.setDisplayMode(new DisplayMode(DISPLAY_WIDTH, DISPLAY_HEIGHT));
            Display.create();
        }
        catch(LWJGLException exception) {
            exception.printStackTrace();
        }

        while(!Display.isCloseRequested()) {
            Display.update();
        }

        Display.destroy();
    }
}

Answer 1

Did you actually try to render anything?

It sounds like the back buffer contains garbage data, and you're not painting anything in that loop. Every time you invoke the Display.update() it flips the back-buffer, and if you've not painted on it then you get the flickering of garbage data.

Try something like:

while(!Display.isCloseRequested()) {
    GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT);
    GL11.glEnd();
    Display.update();
}

Which clears the display before flipping the back-buffer.

In general, if you don't actually display anything then you're at the whims of the graphics driver and memory as to what ends up on the screen. If I used your code, I see the following in the window:
