--- Comment #15 from Carlos Garcia Campos <cgarcia at igalia.com> ---
I'm checking logs reported in bug #202362.

Oct 04 08:14:31 chargestone-cave org.gnome.Epiphany.Devel.desktop[1896]: Cannot get default EGL display: EGL_BAD_PARAMETER
Oct 04 08:14:31 chargestone-cave org.gnome.Epiphany.Devel.desktop[1896]: Cannot create EGL context: invalid display (last error: EGL_SUCCESS)

This is the initialization of the default display, that is also failing so problem is not specific to wpe renderer. EGL_BAD_PARAMETER must be a previous error, as Miguel suggested, and the only egl call that should happen before the egl display initialization is eglGetPlatformDisplay. It returns a EGL_BAD_PARAMETER when the given platform is not supported, but if that was the case it would always fail. I see we are checking for EGL_KHR_platform_wayland and always passing EGL_PLATFORM_WAYLAND_KHR even when using eglGetPlatformDisplayEXT, but that shouldn't be a problem because EGL_PLATFORM_WAYLAND_KHR and EGL_PLATFORM_WAYLAND_EXT are both defined as 0x31D8. 

Oct 04 08:14:32 chargestone-cave org.gnome.Epiphany.Devel.desktop[1896]: Cannot get default EGL display: EGL_BAD_PARAMETER
Oct 04 08:14:32 chargestone-cave org.gnome.Epiphany.Devel.desktop[1896]: PlatformDisplayLibWPE: could not create the EGL display: EGL_SUCCESS.

And this is creating the share display for compositing. In this case I don't know here the EGL_BAD_PARAMETER comes from.
