Bug ID: 424729
Summary: system settings aborted while scrolling through
systemd units because its Wayland connection broke
Product: systemsettings
Version: 5.19.3
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: matthew.fagn...@utoronto.ca
Target Milestone: ---
Application: systemsettings5 (5.19.3)
Qt Version: 5.14.2
Frameworks Version: 5.72.0
Operating System: Linux 5.8.0-0.rc6.20200723gitd15be546031c.1.fc33.x86_64
x86_64
Windowing system: Wayland
Distribution: Fedora 33 (KDE Plasma Prerelease)
-- Information about the crash:
- What I was doing when the application crashed:
I was using Plasma 5.19.3 on Wayland in a Fedora Rawhide KDE Plasma spin
installation with KF 5.72 and Qt 5.14.2. I opened System settings. I selected
systemd at the bottom of the left menu. I scrolled up and down the systemd
units for up to 15 seconds. System settings showed Not responding in its top
bar, and its colours faded. System settings aborted with the error "The Wayland
connection broke. Did the Wayland compositor die?" System settings aborted 3
out of 3 times I did the steps above. I've seen system settings, plasmashell,
konsole, ksysguard and others abort with the same error.

https://bugs.kde.org/show_bug.cgi?id=413901 The problem is likely in qtwayland.
The crash can be reproduced every time.
