Bug Description
GPU apps seem to work.
CPU apps all get black screen.
To repro :
Under unity7 using mir-on-x:
1- In a terminal, run :
mir_demo_server -f /tmp/mysock
2- In another terminal, run :
mir_demo_server --host-socket /tmp/mysock
3- In another terminal, run :
mir_demo_
Under Unity8 :
In another terminal, run :
mir_demo_
Observe that, the window is black.
Whereas, egl clients run fine.

I can't reproduce this (on Radeon, on Zesty). Both GPU and CPU clients render fine in mir_demo_server.
