It's a driver problem.

I'm not entirely sure what you want here. Yes, it's a known problem
in Ubuntu, and upstream. There are plenty of people who can do
something about it, though, by working with upstream to actually
resolve the problems.

I can't speak for the X team, but from what I've gathered the team is
looking at, in roughly this order:
a) Whether UXA can be enabled by default. This is where upstream is
going, and doesn't suffer from the (apparently terrible) performance
problems, but it's much less tested and doesn't seem to to work
properly for everyone.
b) Really, really hoping the upstream Intel drivers have the EXA
performance regressions fixed.
c) Work out whether we can ship an older driver release.
I don't think it's possible to state whether or not this regression
will remain in the final release at this point. There's still a fair
amount of time left to fix it.
