Bug ID: 459623
Summary: kwin_wayland crashed when I pressed alt+tab after
Plasma crash
Classification: Plasma
Product: kwin
Version: 5.25.90
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: bugsefor...@gmx.com
Target Milestone: ---
I repeatedly tried to drag a url from the url bar of Firefox running on
Xwayland to my desktop.
At some point Plasma crashed but coredumpctl gave me no coredump of Plasma. I
ran plasmashell with GDB,
pressed alt+tab, kwin_wayland crashed and all running apps were aborted.
Operating System: Arch Linux
KDE Plasma Version: 5.25.90
KDE Frameworks Version: 5.98.0
Qt Version: 5.15.6
Graphics Platform: Wayland
