Bug description:
After running mir_demo_server on VT 1, when I switch to VT 7 then back to VT
1, the demo server really flickers black quite a lot (entire screen, pointer
included). I'm not sure, but I also upgraded my kernel to 3.18.2-031802-generic
at the same time, if it's because of that, please mark invalid.
