Update Known Issues on Mir installation page?

[Daniel van Vugt]

Joe,

The distortion around the mouse cursor is known:
https://bugs.launchpad.net/xmir/+bug/1218735

And the general skipping/freezing I think is covered by:
https://bugs.launchpad.net/xmir/+bug/1216472

Both bugs have workarounds you can try.

Those are significant bugs which confuse and mask each other. I don't 
think it would be useful to hypothesize about further display bugs until 
they're squashed and out of the equation.

- Daniel
