Is there any update? Thanks.

The driver is correct. The test isn't. The test creates the GL context using the compatibility profile, but expects the behavior of the GL core profile.

The difference is in the default value of GL_DEPTH_TEXTURE_MODE, which is GL_LUMINANCE for GL compatibility and GL_RED for GL core.
