Description of problem: Working on a KDE/Plasma desktop, on a 3D cube with compiz : firefox, thunderbird, dolphin, libreoffice are running fine. After a while, the panel does not respond on click. Contextual menu on the desktop does not show up. But the mouse over on opened applications icons in the panel, are still showing up the thumbnails.

Previously, after killing a faulty session, when landing on the login screen, I've got a kde debugging window with some data. Unfortunately, I did not manage to save anything as I was not logged. Is there a way ? I'm thinking about creating a world writable directory in /home/, or in /tmp/ partition...

Created attachment 9451 [details] xmessage : Could not start ksmserver. Check your installation. (okay) Still reproducing When the panel is freezed, I kill the session Ctrl+Alt+Backspace (twice) Briefly, the screen shows a black screen with some lines (blaw blaw... stolen region...) Then the login screen with a little black and white popup that disappears quickly I login The KDE/Plasma desktop is back, with all previous windows opened AND still with the little popup (see attachment) It says : xmessage : Could not start ksmserver. Check your installation. (+ button okay)
Created attachment 9452 [details] ksmserver - Segmentation fault - KCrash Handler When I click on okay button, the session is killed again ! The black and white popup is still briefly here Then I got a window to debug on the login screen (may be KCrash Handler), and I manage to save the kcrash stack file (see attachment)
I think the bug may begin when I plug an USB stick, that's happening right now. On the other hand, it's the first time I see the "new peripheral notification" freezing. Already launched apps are still running fine.
I manage to restart panel directly from Plasma Desktop with KRunner: Alt+F2 - killall plasmashell then Alt+F2 - plasmashell
Version: Cauldron => 6
Created attachment 9711 [details] panel screenshot showing messy windows icons I don't know if it can help, but got the bug again. Despite restarting plasmashell as explained, the plasma desktop was still not working. Tried to restart it twice. It maybe a coincidence, but thunderbird was struggling sending an email, so I had two thunderbird windows, while trying to restart plasmashell twice or more. (see panel weird screenshot)
