    EGL_ALPHA_MASK_SIZE, EGL_COLOR_BUFFER_TYPE, EGL_LUMINANCE_SIZE, and EGL_RENDERABLE_TYPE are supported only if the EGL version is 1.2 or greater. While EGL_MATCH_NATIVE_PIXMAP can be specified in the attribute list passed to eglChooseConfig , it is not an attribute of the resulting config and cannot be queried using eglGetConfigAttrib .

      The color buffer size is the sum of EGL_RED_SIZE, EGL_GREEN_SIZE, EGL_BLUE_SIZE, and EGL_ALPHA_SIZE, and does not include any padding bits which may be present in the pixel format. It is usually preferable to specify desired sizes for these color components individually.

  3. Special: by larger total number of color bits (for an RGB color buffer, this is the sum of EGL_RED_SIZE, EGL_GREEN_SIZE, EGL_BLUE_SIZE, and EGL_ALPHA_SIZE; for a luminance color buffer, the sum of EGL_LUMINANCE_SIZE and EGL_ALPHA_SIZE).

    Not sure using eglGetConfigAttrib could get the fastest default values.. If EGL_COLOR_BUFFER_TYPE == EGL_RGB_BUFFER, then check the EGL_RED_SIZE, EGL_GREEN_SIZE, EGL_BLUE_SIZE, and EGL_ALPHA_SIZE, total equals to EGL_BUFFER_SIZE..

    As you can see, i added EGL_ALPHA_SIZE attribute and removed EGL_DEPTH_SIZE, since my application is a simple 2D drawing on a surface and it doesn't need a depth buffer. It works, but for some reason results in somewhat unexpected results for this simple fragment shader:
