After running offscreen rendering a few times, I get the following error.

I'm using EGL, i.e., PYOPENGL_PLATFORM=egl , Python 3.7.5, nvidia-450 and Ubuntu 16.04.

Same issue here. I'm on Ubuntu 18.04, Python 3.6.12, and nvidia 435.21.

          In my case, my problem was creating the offscreen renderer within every loop (i.e., calling render = pyrender.OffscreenRenderer). It works okay 'osmesa' as the pyopengl platform. But, for 'egl', it seems to have a problem with automatically get rid of opengl related things. So I just put renderer.delete() that will call the self.delete() of the OffscreenRenderer inside the loop. Hope it helps.

          @SuwoongHeo I don't understand what you saying. I got same rror:
/OpenGL/error.py", line 228, in glCheckError
    raise GLError(
OpenGL.error.GLError: GLError(
	err = 12290,
	baseOperation = eglMakeCurrent,
	cArguments = (

@jinfagang Just add renderer.delete() at the next line of rgb, depth = renderer.render(scene, flags=pyrender.RenderFlags.RGBA)  as @SuwoongHeo said, that works for me.
