Dear Daniel,

Thanks for clarification and for updating the wiki page.  By coincidence today I 
decided to give Mir a spin, installing unity-system-compositor from universe: 
libmirserver1 is version 0.0.10+13.10.20130829.2-0ubuntu1.

This is on a ThinkPad T420, graphics:

     VGA compatible controller: Intel Corporation 2nd Generation Core Processor 
Family Integrated Graphics Controller (rev 09)
     Subsystem: Lenovo Device 21ce
     Kernel driver in use: i915

There's a lot of distortion around the mouse cursor, particularly when moving it 
slowly or when there is a heavy-ish load on the system.

Doing anything like playing a video (e.g. YouTube) seems to slow everything down 
a lot, the video is choppy and there is distortion elsewhere on the screen (e.g. 
while typing this email, there is distortion around the letters I'm typing as 
they appear).  Sometimes during a heavy system load the display will even 
freeze, although this doesn't appear to be a crash -- other things (such as 
audio playback) will continue, and the display unfreezes itself after a period 
of time (e.g. if a video ends).

Multi-monitor seems broadly OK although once when I Ctrl-Alt-Del'd to try and 
escape a frozen display, I wound up with both laptop and external screen active 
and was unable to reconfigure the system to use just the external display 
without a restart.

I'm not sure to what extent these are known issues and given how vague the 
report is I wasn't sure whether to turn this into a bug report or a report on 
the wiki page Jono Bacon set up:
https://wiki.ubuntu.com/Mir/GPUTesting

So, I thought I'd put it on record here -- let me know if you'd like it written 
up either on Launchpad or the wiki and I'll do so.

Thanks & best wishes,

        -- Joe
