Not much. UXA/none adds in hw DRI support (with the caveat that any
DRICopyRegion is going to be very slow), Xv overlay support, rotation
and is slower.

(Normal none, in addition to that, is many times faster, has native hw
rotation support, greater variety of hardware planes support and more
flexible screen configuration, supports TearFree updates and probably
many more that I missed off the top of my head.)
