I have two theories at least:
1. modesetting can't deal with hiDPI very well; or
2. compiz/unity7 is falling back to software rendering under the modesetting
driver.
Can you please test #2? Just tap the Super key to open the Unity7 dash.
Is it translucent or solid coloured?
Also, failure to set correct permissions for /dev/dri/* I think is
lightdm's problem. So adding lightdm here.
