# 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. ** Affects: qtdeclarative-opensource-src (Ubuntu) Importance: Medium Assignee: Timo Jyrinki (timo-jyrinki) Status: Confirmed ** Affects: qtdeclarative-opensource-src (Ubuntu Vivid) Importance: Medium Status: Confirmed ** Affects: qtdeclarative-opensource-src (Ubuntu Wily) Importance: Medium Assignee: Timo Jyrinki (timo-jyrinki) Status: Confirmed -- Qt5 applications crash when switching screens https://bugs.launchpad.net/bugs/1450137 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to the bug report. -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
