Hi,
  His problem is caused by internationalized input handlers, not Wayland.

Wayland does present many annoying issues, but most of them are related to lack
of support for high-end graphics technologies like stereoscopic rendering
and the like. All of the graphics technologies that have trouble
with the X11 composite extension have problems on Wayland also.
Wayland kills off support indirect GLX rendering, so you can't
remote display anymore.

I think some of the biggest issues are just that Wayland isn't supported
by NVIDIA because it requires/enforces particular driver architecture that
isn't workable for various reasons, and neither side of that argument
has found a compromise that everyone can live with yet.

My advice to anyone reading is to stay clear of Wayland until the
dust settles, which might be a couple more years at the rate things
are progressing. In my view Wayland is solving no problems that matter
to me, and it is designed and implemented in a way that doesn't appear
to coexist well with the existing ecosystem of graphics technologies and
X11 features that have been around for decades. I personally don't need
an extra window compositor slowing down my graphics pipeline and breaking
things like quad-buffered stereoscopic rendering, but that's just my
personal opinion. :-)

Best,
  John
