Upstream has struggled for a long time with these problems, and we have plenty of backported fixes from Qt 5.6 branch in our 16.04's Qt 5.5. Sadly they don't fix all issues still.
The next upload is already being prepared and is at https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-016 if you want to test and report back if there is any change for you. It has yet another two patches to these issues and some other patches that are not related. So you could test it with: sudo apt-add-repository ppa:ci-train-ppa-service/landing-016 sudo apt update sudo apt dist-upgrade And later downgrade back (please do, to remove the PPA from system, the contents will change): sudo apt install ppa-purge sudo ppa-purge ppa:ci-train-ppa-service/landing-016 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1551122 Title: Crash on screen power save Status in qtbase-opensource-src package in Ubuntu: Fix Released Bug description: Continuation to bug #1548766 to consider another upstream fix from https://codereview.qt-project.org/#/c/138681/ The fix could affect both monitor power saving or attaching/detaching cycles.
