Bug ID: 421047 Summary: Wayland - Crash on Wallpaper settings (or mesa upgrade) Product: plasmashell Version: 5.18.4 Platform: unspecified OS: Linux Status: REPORTED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: k...@davidedmundson.co.uk Reporter: ja...@jasonplayne.com CC: plasma-b...@kde.org Target Milestone: 1.0 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 Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
