Sentry Crash Report:

Description Ilya Sheershoff 2016-10-19 13:11:27 UTC 
- What I was doing when the application crashed:

I chose one of the windows from the list of open google-chrome windows, then clicked on the tab I needed, the system hang up and then the message about crash appeared

- Noticed strange behavior:

The panel popup with the list of windows didn't disappear after I clicked on the window I needed. I managed to click on the tab I needed with the list of windows on screen.

Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 4.4.0-42-generic x86_64
Distribution: Ubuntu 14.04.5 LTS

Comment 3 Nate Graham 2018-06-08 18:33:09 UTC 
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!

Nate Graham
