After bisecting, the following commits seems to be the cause:

    egl: Check if API is supported when using eglBindAPI.

    According to the EGL specifications before binding an API
    we must check whether it's supported first. If not eglBindAPI
    should return EGL_FALSE and generate a EGL_BAD_PARAMETER error.
