Description John Werner 2021-04-15 13:20:55 UTC

Application: krunner (5.19.5)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-49-lowlatency x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

-- Information about the crash:
- What I was doing when the application crashed:

Logging out of KDE session
1. clicked KDE's "start menu" button
2. selected "Leave"
3. selected "Log Out"
4. crash.

This was tried 3 times in the same session with the same result.

- Unusual behavior I noticed:

Open GL drivers disappeared. May be related to recent 'apt dist-upgrade'.

The crash can be reproduced sometimes.

-- Backtrace:
Application: krunner (krunner), signal: Aborted

> QSGRenderLoop::handleContextCreationFailure
Yes this means your graphics drivers are messed up after upgrading and things won't work right until after a reboot.

We have code to work around this (see https://invent.kde.org/frameworks/kdeclarative/-/merge_requests/37), but perhaps KRunner isn't using the init function that goes through that codepath?

Oh, actually it's that you're using an old version where it's not fixed yet. :)
