Comment 12 for bug 1528384

We're needing more data on this bug, and we're going to eventually land the MP's to improve some reporting.

But this bug is critical, and we'd like to get information as soon as possible.
_Only_ if you are willing to risk not getting autoupdates (and have to flash your phone in future) - you can try the improved reporting for mir & unity-system-compositor by installing
https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-014
you'd need to be on OTA9.5 or latest rc-proposed image.

If you install this ci-train silo and experience this bug, we are highly interested in the /var/log/lightdm/unity-system-compositor.log

I'll follow up once we land these reporting improvements in the image and the silo is no longer needed.
