GLFW3 failed to initialize on Weston 5.0.0

GLFW3 (wayland backend) failed to initialize on Weston 5.0.0 (backend is x11-backend.so) The error code got from the error callback function of GLFW is 65544, the description of which is EGL: Failed to create window surface: ERROR: UNKNOWN EGL ERROR

surface = eglCreatePlatformWindowSurface(
	display,		// returned from eglGetPlatformDisplay(EGLenum, void *, const EGLAttrib *)
	_eglConfig, 		// returned from eglChooseConfig(EGLDisplay, const EGLint *, EGLConfig *, EGLint, EGLint *)
	nativeEGLWindow,	// returned from wl_egl_window_create(struct wl_surface *, int, int)
	windowAttrib		// const array of EGLAttrib
);

The eglCreatePlatformWindowSurface just returned EGL_NO_SURFACE and set the error code to 0x3008, which is EGL_BAD_DISPLAY defined in /usr/include/EGL/egl.h. I am sure that the EGL Display has already been initialized with eglInitialize returned EGL_TRUE. According to the EGL specification this is not the correct behavior.

I am willing to help debug but I do not know what to do after tracing into libglfw.so or libEGL.so without debugging symbols in gdb.

GLFW3 (wayland backend) failed to initialize on Weston 5.0.0 (backend is ```x11-backend.so```)
The error code got from the error callback function of GLFW is ```65544```, the description of which is ```EGL: Failed to create window surface: ERROR: UNKNOWN EGL ERROR```

And I tested one of my demos which was written when I was learning Wayland protocol and EGL to get more information.
My program still works on Gnome (wayland backend) now.
But on Weston 5.0.0, I find it failed at the following line in my program:
```
surface = eglCreatePlatformWindowSurface(
	display,		// returned from eglGetPlatformDisplay(EGLenum, void *, const EGLAttrib *)
	_eglConfig, 		// returned from eglChooseConfig(EGLDisplay, const EGLint *, EGLConfig *, EGLint, EGLint *)
	nativeEGLWindow,	// returned from wl_egl_window_create(struct wl_surface *, int, int)
	windowAttrib		// const array of EGLAttrib
);
```
The ```eglCreatePlatformWindowSurface``` just returned ```EGL_NO_SURFACE``` and set the error code to ```0x3008```, which is ```EGL_BAD_DISPLAY``` defined in ```/usr/include/EGL/egl.h```.
I am sure that the EGL Display has already been initialized with ```eglInitialize``` returned ```EGL_TRUE```.
According to the EGL specification this is not the correct behavior.

I am willing to help debug but I do not know what to do after tracing into ```libglfw.so``` or ```libEGL.so``` without debugging symbols in gdb.
