I think it starts to sound like it would be useful to land this fix in wily to get also more exposure to the fix, but maybe not worth starting an SRU at this point. The impact seems to be either a) low or b) a bit unpredictable on the actual problem users are seeing. If it turns out we can get also other fixes landed to wily and they together would have a bigger improvement, the SRU could be considered later?

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.
