This issue has been present since at least v3.1.0-stable, so it's not a recent regression.

[stephengold]

Thanks, Riccardo!

[riccardobl]

I am testing this with the master branch, can't reproduce. Is this happening also with lwjgl3?

If you are still able to reproduce it, can you try change lines 1787-1790 in GLRenderer.java from

        if (context.boundRB != id) {
            glfbo.glBindRenderbufferEXT(GLFbo.GL_RENDERBUFFER_EXT, id);
            context.boundRB = id;
        }

to

        //if (context.boundRB != id) {
            glfbo.glBindRenderbufferEXT(GLFbo.GL_RENDERBUFFER_EXT, id);
            context.boundRB = id;
        //}

causing the framebuffer to be rebound every call, in case we are dealing with some sort of driver issue that unbounds the framebuffer...

[stephengold]

Thank you for your investigations so far.
I just now reproduced the issue in the latest "master" branch, but only with LWJGL v2.
With LWJGL v3, I failed to reproduce the issue.
I tried commenting out the id test per your suggestion, in "master" with LWJGL v2, and this resolved the issue.

[riccardobl]

Mhh, what is the value of fbOnLoad in GLRenderer line 637 ?

[stephengold]

In the "v3.4" branch with LWJGL v2, it's 0.

[stephengold]

If you're convinced this is a driver bug with no obvious workaround, then let's close this issue.

[riccardobl]

I am not entirely sure, i'd like to investigate it some more

[stephengold]

Okay. Let me know if I can assist in any way.

[stephengold]

I reproduced the crash on different hardware (GeForce RTX 2070), running Windows 10, so apparently it's not driver-specific.
I'm still seeing the crash only with LWJGL 2.9.3, not with LWJGL 3.

[Ali-RS]

I can not reproduce the crash. I am testing on Linux with LWJGL 2 and Mesa graphics driver.

Because of the following code

jmonkeyengine/jme3-lwjgl/src/main/java/com/jme3/system/lwjgl/LwjglAbstractDisplay.java

Line 166 in aaabd10

assert checkGLError();

assertions must be enabled in order to reproduce this crash.

@Ali-RS Please check whether assertions are enabled in your test environment.
