Bug ID: 468576
Summary: Middle-clicking certain widgets in a panel crashes
plasmashell
Classification: Plasma
Product: plasmashell
Version: 5.27.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Panel
Assignee: plasma-b...@kde.org
Reporter: ryuichi.ya...@gmail.com
CC: niccolo.venera...@gmail.com
Target Milestone: 1.0
SUMMARY
Middle-clicking on some panel widgets (e.g. to mute all speakers) crashes
plasmashell.
STEPS TO REPRODUCE
1. Middle-click the volume panel icon
OBSERVED RESULT
Crashes plasmashell
EXPECTED RESULT
Does not crash plasmashell
SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 37
KDE Plasma Version: 5.27.4
KDE Frameworks Version: 5.104.0
Qt Version: 5.15.8
Kernel Version: 6.2.10-200.fc37.x86_64 (64-bit)
Graphics Platform: X11
ADDITIONAL INFORMATION
I'm using Breeze as my application style theme. It also happens on a Wayland
session.
On my system, middle-clicking the titlebar buttons crashes KWin as well. So it
might not be an issue in plasmashell but in Qt or something.
