Summary: KWin crash
Product: kwin
Version: 5.12.5
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: eg...@protonmail.com
Target Milestone: ---
Application: kwin_x11 (5.12.5)
Qt Version: 5.10.1
Frameworks Version: 5.46.0
Operating System: Linux 4.16.8-1-ARCH x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Using a console-based text editor (Word Grinder), and accidentally opened a
second tab (CTRL+SHIFT+W). I got two views of the same program, one above the
other, while the screen flickered for a moment. Then I got the notification
that KWin had crashed.
The crash does not seem to be reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
