Committed on 10/03/2017 at 11:16. Pushed by mart into branch 'Plasma/5.8'. try proper order of corona()->availableScreenRect() Summary: connect to Plasma::Corona::availableScreenRectChanged instead of using kscreen, this way we should be more sure that signal is emitted when it's safe to call corona()->availableScreenRect() as the change of rect may happen after a screen removal, so may mean accessing a desktop view while being deleted Test Plan: notifications still pop up in the proper place, couldn't reproduce the crash neither before nor after tough Reviewers: #plasma, davidedmundson Reviewed By: #plasma, davidedmundson Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D4991 M +3 -4 applets/notifications/lib/notificationsapplet.cpp M +1 -1 shell/shellcorona.cpp https://commits.kde.org/plasma-workspace/bcb6b86d3ab8bd196877473af343b72c53e4f932 1668713 5 kde 2017-03-27 16:47:20 +0000 *** Bug 378151 has been marked as a duplicate of this bug. *** 1670854 6 notmart 2017-04-11 13:51:56 +0000 *** Bug 378508 has been marked as a duplicate of this bug. ***
