Bug Description
I've installed Mir on an old Samsung netbook (N310) with an Atom CPU and onboard graphics. Everything seems to be normal, expect when I open the dash the following happens:
1.) Press the Super key to open the Dash
2.) Wait 60 seconds
3.) A 'ghost' of the Dash appears (high alpha value)
4.) Wait 60 more seconds
5.) Dash is at last usable
Closing the Dash works at the usual speed (not instant but acceptable)

Logs all seem to indicate it is an accelerated X session - Chris, any idea what might be happening here?
Brendan - I assume this does work fast when XMir is not enabled?
