Bug ID: 496712
Summary: Taskmanager crashes repeatedly after trying to render
a window preview (caused by mouse hover over
LibreWolf, system settings, etc.)
Classification: Plasma
Product: plasmashell
Version: 5.27.11
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Task Manager and Icons-Only Task Manager
Assignee: plasma-b...@kde.org
Reporter: krystof...@gmail.com
CC: qydwhotm...@gmail.com
Target Milestone: 1.0
SUMMARY
Taskmanager ("classic taskbar-style window switcher displaying icons and text")
repeatedly crashes after I hover over open windows. It does not matter what
application window I hover over, but the issue is mainly triggered by hovering
over Firefox / LibreWolf, although not exclusively.
STEPS TO REPRODUCE
1. Set-up the classic taskbar widget
2. Enable the preview window when hovering over tasks option
3. Panel crashes after hovering over web browser tasks (after a short while)
OBSERVED RESULT
Whole Plasma environment stops responding. Already running tasks are usable and
respond, but the desktop environment itself dies off.
The crash is recoverable by executing killall plasmashell; nohup plasmashell &
but this is unusable for most users.
EXPECTED RESULT
Panel not to crash.
