For context, this crashes my application

canvas = new GLCanvas(
                    LWJGLExecutor.LWJGL_MODULE,        // executor
                    false,                             // flipY
                    0,                                 // msaa
                    0.0,                               // fps
                    1,                                 // swapBuffers
                    GLInteropType.Companion.getAuto(), // interopType
                    GLProfile.CORE,                    // profile
                    false,                             // glDebug
                    null,                              // shareWith
                    -1,                                // majorVersion (Defaults.MAJOR_VERSION)
                    -1,                                // minorVersion (Defaults.MINOR_VERSION)
                    false                              // externalWindow
            );

Tried GLProfile.COMPATIBILITY and swapBuffers 2 but it did not work.

Have you tried 4.2.2? There were changes right in this place. It also let you use GLCanvas.Builder instead of constructor in Java.

[husker-dev]

Got it

[streamingdv]

@husker-dev sorry my mistake, I'm already using version 4.2.2 but same crash occurs on 4.2.0 and 4.2.1 I just tried. It crashes immediately when creating the Canvas.

[husker-dev]

Are you using Wayland? If so, have you disabled X11 support?

[husker-dev]

Also, try calling this function at the beginning of the program launch: GLManager.setPreferGLX(false);

[husker-dev]

Also try to install glxinfo (from mesa-utils) and launch it in terminal. And show what it prints please.

[streamingdv]

@husker-dev Yes I use wayland, what do you mean by disabling X11 support? You mean falling back to X11 Window manager?

Called this GLManager.setPreferGLX(false); in my main method it crashed again but with a different error and crash log

Here is the glxinfo information

[husker-dev]

Wayland has a module for backwards compatibility with X11 (it also includes GLX). I'm not sure, but some people may disable it. If you haven't done anything, then it's probably on.

As I understand it, you have some kind of integrated Intel graphics, right?

[streamingdv]

@husker-dev yes I have an integrated Intel GPU but i my notebook also has a Nvidia GPU. On the Nvidia GPU it works more or less in certain conditions but I need to check it in more details. I have to force the Nvidia GPU via command line, it's just something which worked in 4.0.5 without any such modifications

[streamingdv]

@husker-dev just experimented a bit and downgrading to version 4.0.5 on Linux fixes the crash. It works fine without crashing on both my Intel and Nvidea GPU.
