Description Jason Playne 2020-05-05 08:36:16 UTC 
Application: plasmashell (5.18.4)

Qt Version: 5.14.2
Frameworks Version: 5.69.0
Operating System: Linux 5.6.7-050607-generic x86_64
Windowing system: Wayland
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:
While I was waiting for discover to upload to the mesa 20.1 RC1 release I was fiddling with my wallpaper settings.

I have a dual monitor setup (2x1080p) with 1 hdmi and one DP->DVI monitor

- Unusual behavior I noticed:

The screen flickered (like it was attempting to recover?) and then crashed the desktop session crashed with only my apps left open. The wallpaper settings page is no longer around.

- Custom settings of the application:

I am using a PPA

deb http://ppa.launchpad.net/ernstp/mesarc/ubuntu bionic main

for mesa stable releases

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted

Based on the duplicate bug report Bug 421446, it looks like kwin_wayland crashed. We will need a backtrace of that crash, if it is still reproducible. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks!
