 146        * The problem, as of 2017-05-30:
 147        * When matching a GLXFBConfig to a __DRIconfig, GLX ignores the channel
 148        * order and chooses the first __DRIconfig with the expected channel
 149        * sizes. Specifically, GLX compares the GLXFBConfig's and __DRIconfig's
 150        * __DRI_ATTRIB_{CHANNEL}_SIZE but ignores __DRI_ATTRIB_{CHANNEL}_MASK.
 151        *
 152        * EGL does not suffer from this problem. It correctly compares the
 153        * channel masks when matching EGLConfig to __DRIconfig.
