Application: plasma-desktop (4.11.22) KDE Platform Version: 4.14.21 Qt Version: 4.8.7 Operating System: Linux 4.4.38 x86_64 Distribution (Platform): Slackware Packages -- Information about the crash: - What I was doing when the application crashed: Unlocked the task bar panel. Chose to add new widgets. Typed "not" to find "KNotes" Captured "KNotes" by mouse and dragged to the right-bottom screen corner. I just tried to collapse all app windows to see the clean desktop. As the Plasma configured such: if the mouse pointer is in the right-bottom corner of the screen, all app windows should collapse. But happen sth strange. The dragging stopped & a gray rectangle appeared to the right of the clock widget. Then I tried to remove that rectangle. Clicked much time on it & so on. No effect. Then near of it right-click -> remove the widget "Panel" -> ...

Hello! This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug has already been resolved in Plasma 5. Accordingly, we hope you understand why we must close this bug report. If the issue described here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging Thanks for your understanding!
