LWJGLException when switching from full-screen to windowed context #798

stephengold · 2018-01-11T22:19:00Z

If I start a JME application in windowed mode, I can switch to full-screen mode at any time, provided my settings match one of those supported by my graphic adapter.

However, if I start in full-screen mode, any attempt to switch to windowed mode crashes the application.
I see this issue with both JME 3.1.0-stable and JME 3.2.0-stable

Here is my test app:

package mygame;

import com.jme3.app.SimpleApplication;
import com.jme3.input.KeyInput;
import com.jme3.input.controls.ActionListener;
import com.jme3.input.controls.KeyTrigger;

public class Main extends SimpleApplication {

    public static void main(String[] args) {
        Main app = new Main();
        app.start();
    }

    @Override
    public void simpleInitApp() {
        inputManager.addMapping("goWindowed", new KeyTrigger(KeyInput.KEY_P));
        ActionListener listener = new ActionListener() {
            @Override
            public void onAction(String name, boolean keyPressed, float tpf) {
                if (name.equals("goWindowed") && keyPressed) {
                    goWindowed();
                }
            }
        };
        inputManager.addListener(listener, "goWindowed");
    }

    void goWindowed() {
        settings.setFullscreen(false);
        setSettings(settings);
        restart();
    }
}

Here is typical output:

Hi, I did the test with the code but I do not have this problem. The program continues to function without getting stuck. I'm using JME 3.2

stephengold · 2018-01-17T02:46:21Z

If you haven't already, try launching in full-screen mode and then pressing the "P" key.

stephengold · 2018-01-17T03:59:12Z

After further investigation, it seems that the exception isn't raised unless the initial display mode has a color depth of 16 bits per pixel. If the initial mode has a color depth of 32 bits per pixel, the switch to windowed mode goes smoothly.

thoced · 2018-01-17T07:41:17Z

This problem may be related to your issue:

#801

empirephoenix · 2018-01-17T08:23:10Z

Well the os is useing 32bit for framebuffers in the window manager, maybe it is an invalid call to create a window with 16bit (and lwjgl will do just that)?

stephengold · 2018-01-17T09:04:21Z

This does seem connected to issue #801. But in 801, there's no exception raised.

stephengold · 2018-09-19T20:05:06Z

Need to re-test with both LWJGL v2 and v3.

stephengold · 2022-04-03T07:41:43Z

Still seeing this issue with LWJGL v2 but not with v3.

With my improved understanding of LWJGL, I suspect this issue is fixable.

stephengold · 2023-03-21T07:02:30Z

I'm still seeing this issue with JME 3.6.0-stable (LWJGL v2.9.5).

Ali-RS · 2023-03-21T10:50:07Z

I can not reproduce this. Tried with 3.6.0-stable.
Works fine for me with both lwjgl2 and lwjgl3.

Edit:

it seems that the exception isn't raised unless the initial display mode has a color depth of 16 bits per pixel.

In my case the only available color depth is 24 bpp when fullscreen is selected.

Edit2:

I noticed if I change

    void goWindowed() {
        settings.setFullscreen(false);
        setSettings(settings);
        restart();
    }

to

    void goWindowed() {
        settings.setFullscreen(false);
        settings.setDepthBits(32);
        setSettings(settings);
        restart();
    }

I get this exception when switching from full-screen:

and if I change it to

    void goWindowed() {
        settings.setFullscreen(false);
        settings.setDepthBits(16);
        setSettings(settings);
        restart();
    }

it shows a blank window after switching. (no spatial is rendered in the viewport)

Maybe changing color depth is not supported with context restart.

I made a commit to the master branch that may fix this issue, please re-test this from the master.

Feel free to reopen it if you still have the issue.

stephengold · 2023-03-28T21:51:52Z

I reproduced the issue on Mint Linux using 3.6.0-stable. Then I ran the same test using jMonkeyEngine master branch at Git Hash 365759d and was unable to reproduce the issue. So I think it's solved.

Thank you, @Ali-RS!
