[Bug] Other software producing errors in my context?

« on: January 03, 2021, 08:42:00 »

It seems like many screen recording devices, but also some other software keep crashing my app by producing openGL errors.

Code: [Select]

[LWJGL] OpenGL debug message
                ID: 0x500
                Source: API
                Type: ERROR
                Severity: HIGH
                Message: GL_INVALID_ENUM error generated. Operation is not valid from the core profile.

I realize this is no fault of LWJGL, but what is the preferred workaround? I like keeping my code clean, by not accepting any errors, but this makes it impossible.

A way of reproducing is just trying to stream an app with discord. I'm using opengl 3.3 core profile, maybe that's important.

Well, it would certainly be interesting why exactly a GL_INVALID_ENUM is created there. More context is needed.

A good way to debug this might be to enable the debugging context:

Code: [Select]

glfwWindowHint(GLFW_OPENGL_DEBUG_CONTEXT, GLFW_TRUE);

Here are some examples:

Code: [Select]

        ID: 0x502 
        Source: API 
        Type: ERROR 
        Severity: HIGH 
        Message: GL_INVALID_OPERATION error generated. Function glPushAttrib is deprecated and not available in preview contexts.

        Severity: HIGH 
        Message: GL_INVALID_OPERATION error generated. Function glPopAttrib is deprecated and not available in preview contexts.

I'm not calling these functions in my app. Somehow the external apps must hijack my context and do these things?

Examples of capture software that breaks stuff:

Discord, EaseUS RecExperts and oCam

Any way to fix this? Or just start polling and ignoring errors?

Here are some from discord:
