Summary: KWin crashes when title of a window changes
Product: kwin
Version: 5.8.7
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: anvar...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.8.7)
Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.4.0-79-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I am writing a text note in Kate, and when I saved the note (and window title
changed), KWin crashed.
In addition, I had some other applications opened, like Firefox, Dolphin,
Telegram Desktop or Avidemux.
The crash can be reproduced sometimes.
