Description Andrew Knackstedt 2019-12-24 15:48:36 UTC 
Application: plasmashell (5.17.4)

Qt Version: 5.13.2
Frameworks Version: 5.65.0
Operating System: Linux 5.0.0-37-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
I created 15-20 stick note widgets via the middle mouse click button. I then started removing them one-by-one. After removing a number of them, plasma crashed and immediately rebooted. I then started removing more of them, and plasma crashed again.
- Unusual behavior I noticed:
Plasma was gitchy when removing the sticky note widget. The KWin desktop effects seem to be working as intended. I can still use the alt-tab task switcher, and I have the KWin performance monitor enabled.


Using KDE-Neon distro. Installed 2 days ago.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Comment 1 Andrew Knackstedt 2019-12-24 16:34:07 UTC 
I think the crash is due to the plasma notification stack overflowing. The crash happens exactly when the notifications get to 5 high.
Comment 2 gvgeo 2019-12-24 19:45:40 UTC 
This happens with other widgets too.
Something to do with the notifications. Often crashes when mouse passes over the notifications.
Comment 3 Kai Uwe Broulik 2020-01-07 11:26:40 UTC 
The notification isn't the cause, closing the notification merely causes the widget to be actually deleted, where it then crashes.
Seems to crash in qqc2-desktop-style or thereabouts.
Comment 4 Nate Graham 2021-03-18 17:52:58 UTC 
The ToolButton code was rewritten to make better use of the QStyle properties, and we haven't seen any crashes like it since. Can anyone still reproduce this crash with Frameworks 5.76 or later?
