Description Dmitry Ivanov 2021-10-30 14:55:19 UTC 
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

Git commit c5a29b4b66c001c49c5bcf9aa9250d8322eefbbd by David Edmundson.

effects: Make OpenGL context current before deleting framebuffer

When we delete a window we unredirect, when we unredirect, we delete the
framebuffer which requires an openGL context.

handleWindowDeleted is the entry point from workspace events to effects
code, so it's made current here.
