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
