Bug ID: 436215
Summary: System Monitor segmentation faulted in update_buffers
when closing
Product: plasma-systemmonitor
Version: 5.21.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: matthew.fagn...@utoronto.ca
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
Application: plasma-systemmonitor (5.21.4)
Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.16-300.fc34.x86_64 x86_64
Windowing System: Wayland
Drkonqi Version: 5.21.4
Distribution: Fedora 34 (KDE Plasma)
-- Information about the crash:
- What I was doing when the application crashed:
I started System Monitor in Plasma 5.21.4 on Wayland in a Fedora 34 KDE Plasma
installation. I selected History in the left menu. I closed System Monitor.
System Monitor segmentation faulted in update_buffers at
../src/egl/drivers/dri2/platform_wayland.c:670 in
mesa-libEGL-21.0.3-1.fc34.x86_64. I've only seen System Monitor crash once with
this trace. plasmashell occasionally crashed in update_buffers with a similar
trace as I reported at https://bugs.kde.org/show_bug.cgi?id=414411
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: System Monitor (plasma-systemmonitor), signal: Segmentation fault
