Cool. Sounds like a simple problem then, of Mir just failing to schedule
a compositor frame on wakeup.
Normally frames are scheduled only when a surface changes. When no
surface is changing, no frames are scheduled, resulting in better power
management. So the touch is what triggers some surface to change, and
then a frame gets scheduled.
Obviously we need to force a frame to be scheduled when the screen wakes
up, as a special case. If we're not doing it already... (?)
