"Kubuntu Won't be Switching to Mir or XMir"
I think that's rather a bit more than following the advice of your upstream
developers; it looks to me like Jonathan is staking out a position against
Mir. Frankly, this doesn't look to me like an informed decision at all, it
looks like a polemic one. XMir is going to be the X stack that receives the
most attention from Canonical, as well as from other Ubuntu developers
working on Ubuntu-the-flavor. Given that the major concern I've seen
expressed is that the Kubuntu team won't have resources to maintain their
own display stack, I don't see how anyone could have arrived so quickly at
the conclusion that using the XMir stack - the one used by Ubuntu - is
risky, and using the native X stack - not used by Ubuntu - is safe.
Compositing may be fragile, but there should be no difference visible to
KWin between XMir and native X with respect to compositing. And given the
tendency for bugs to arise as a result of mismatches between X+mesa, or
X+mesa+kernel, I would be much more worried about native X not receiving the
attention it needs to be kept in sync with mesa - a problem that won't arise
with XMir, since Mir+mesa are obviously going to be maintained as a usable

So I'm not convinced that XMir actually represents complication for Kubuntu,
rather than beneficial alignment.
Steve Langasek Give me a lever long enough and a Free OS
Debian Developer to set it on, and I can move the world.
