 124        * The problem, as of 2017-05-30:
 125        * When matching a GLXFBConfig to a __DRIconfig, GLX ignores the channel
 126        * order and chooses the first __DRIconfig with the expected channel
 127        * sizes. Specifically, GLX compares the GLXFBConfig's and __DRIconfig's
 128        * __DRI_ATTRIB_{CHANNEL}_SIZE but ignores __DRI_ATTRIB_{CHANNEL}_MASK.
 129        *
 130        * EGL does not suffer from this problem. It correctly compares the
 131        * channel masks when matching EGLConfig to __DRIconfig.
