Hi all, Some of you may have been following the various threads on the "Qt5.2 queuing events when screen is off" bug through any of the following: https://bugs.launchpad.net/mir/+bug/1292306 https://bugreports.qt-project.org/browse/QTBUG-37677 https://lists.launchpad.net/ubuntu-phone/msg07458.html
Short summary on the conclusion, we're working on altering Mir to not block on swapbuffers in the instance of occluded apps & screen off and relying on the shell to enforce the toolkit side channel to halt rendering. Given that this is a significant behavioral change we're taking a systematic approach and hoping to get some additional testing and road-milage before landing. At the moment we have branches available which to deliver the desired change. We welcome anyone who would like to help out by testing... and if you'd like to help, please follow this wiki I threw together. https://wiki.ubuntu.com/Mir/NonBlockingSwapTesting br, kg
