Bug ID: 410093
Summary: KWin crash after switch to/from text console
Product: kwin
Version: 5.16.2
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: memelink.ak...@planet.nl
Target Milestone: ---
Application: kwin_x11 (5.16.2)
Qt Version: 5.13.0
Frameworks Version: 5.59.0
Operating System: Linux 5.1.16-1-default x86_64
Distribution: "openSUSE Tumbleweed"
-- Information about the crash:
- What I was doing when the application crashed:
I switched to a text console (Ctrl-Shift-F1) and switched back to Plasma
(Ctrl-Shift-F7). I got a message that KWin crashed. I chose "restart" and the
UI (including the compositor) is working again.
This is occuring every 2 or 3 days, usually after a "cold start" of the system,
but is not ready reproducible (doesn't happen every time).
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
