The bug https://bugs.kde.org/show_bug.cgi?id=345544 linked from https://bugreports.qt.io/browse/QTBUG-45753 (linked from https://codereview.qt-project.org/#/c/111100/) has a claim from Stefan that he doesn't see a particular crash anymore with Fedora's patched Qt. The only relevant patch in that Fedora qtdeclarative seems to be this same patch, so can maybe someone try to reproduce the crasher described in that bug and then confirm it'd be fixed by the PPA?
That we way we could get at least one crasher fix in for starters. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtdeclarative-opensource- src in Ubuntu. https://bugs.launchpad.net/bugs/1450137 Title: Qt5 applications crash when switching screens Status in qtdeclarative-opensource-src package in Ubuntu: Incomplete Status in qtdeclarative-opensource-src source package in Vivid: Confirmed Status in qtdeclarative-opensource-src source package in Wily: Incomplete Bug description: # Impact When switching screens (e. g. when putting the laptop onto the docking station the notebook screen is turned off and the external one is turned on) Qt5 applications (including plasmashell) quite often crash. # Test Case * Have two screens. One plugged-in one not * Run plasma 5 * Plug-in second screen and wait 10 seconds * Unplug and wait 10 seconds * Plug-in and wait 10 seconds * Unplug and wait 10 seconds * ... # Regression Potential Worst case scenario an application using qquickscreen would slow down because of erroneous screen change singals being emitted too often per second. This would however only reveal a lower level issue in the foundations that ultimately needs to be fixed anyway. # Other Info The upstream code review [1] explains the issue and solution pretty well. https://codereview.qt-project.org/#/c/111100/ --------- original report --------------- When switching screens (e. g. when putting the laptop onto the docking station the notebook screen is turned off and the external one is turned on) Qt5 applications (including plasmashell) quite often crash. This makes my laptop unusable, since I do that very frequently. The problem has already been described here: https://bugs.kde.org/show_bug.cgi?id=341497 Apparently it is fixed in Qt 5.5 I am running Kubuntu 15.04 64bit and libqt5gui5 5.4.1+dfsg-2ubuntu4.
