 148        * The problem, as of 2017-05-30:
 149        * When matching a GLXFBConfig to a __DRIconfig, GLX ignores the channel

 151        * sizes. Specifically, GLX compares the GLXFBConfig's and __DRIconfig's
 152        * __DRI_ATTRIB_{CHANNEL}_SIZE but ignores __DRI_ATTRIB_{CHANNEL}_MASK.
 153        *
 154        * EGL does not suffer from this problem. It correctly compares the
 155        * channel masks when matching EGLConfig to __DRIconfig.
