This is currently an issue for Lubuntu, because, if i understand
correctly, we are going to replace an X + openbox (without composite)
with a Mir + XMir + composite windows manager (?). Considering the
very bad performance on some of our target hardware running under a
composite manager, I'm quite worrying about the performance
difference. The difference between Unity + X and Unity + XMir + Mir
may not be so different, I can't say the same for Lubuntu.

good consideration, I'll check with the QA team to see if we can have a run in this configuration.

thx,
Olli
