Sorry, but this seems like a really naive statement. HW-related bugs
frequently are only exposed by some particular software operation.
Right now it's hardware driver + X + openGL libs. In the future it will
be hardware driver + Mir + openGL + XMir. That is, for Unity. The
Kubuntu people will need to worry about

HW driver + X + openGL
HW driver + Mir + openGL + XMir
HW driver + Wayland + openGL

There are plenty of bugs which never seem to get fixed already under the
less complex scenario; thinking that Mir + XMir is just a lateral shift
which won't make the problem worse is wishful thinking.

In the long run, options and competition will result in a much better
graphics subsystem. Short term, there is likely to be a lot of pain and
frustration, and pretending this won't be the case is going to lead to
(even more) disgruntled users and developers.
