            Bug ID: 444665
           Summary: Kwin crashed after logging in
           Product: kwin
           Version: 5.23.2
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kwin-bugs-n...@kde.org
          Reporter: dm.vl.iva...@gmail.com
  Target Milestone: ---

Application: kwin_x11 (5.23.2)

Qt Version: 5.15.3
Frameworks Version: 5.87.0
Operating System: Linux 5.11.0-38-generic x86_64
Windowing System: X11
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.2 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I just logged into my laptop running KDE Neon 5.23.2 and almost immediately saw
the crash reporter icon in the system tray. I've seen it a couple of times
already but didn't pay much attention. But since it reproduced several times, I
decided it's worth reporting.

The issue might be connected with the fact that the last time the laptop was
on, it had an external monitor connected to it via HDMI cable. And then I
started it up without the external monitor connected.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
