So wait...the screen is off, and Mir isn't rendering...and that's a problem
??
hope that's not what you're saying.
wouldn't be popular for battery operated devices.
In fact there's been some debug to show that there has been a change
identified in Qt which caused this. Crept in between images 237 and 238
which is the Qt5.2 arrival (
https://lists.launchpad.net/ubuntu-phone/msg06947.html). Surely Qt
depending on rendering for all events of every kind is a mistake.
hopefully we'll reach a solution tomorrow.

Still no witness of this as of yet....from anyone on my teams.
If anyone does encounter this, if you can afford to do so, please connect
to your laptop and run top and place that info in the bug. Note, we see no
crash dump here, davmor2 says its strictly a hang.
