Summary: Crash of Kwin-Wayland when the USB-C dock is unplugged
and Firefox is opened
Classification: Plasma

Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: ---
Application: kwin_wayland (6.3.4)
ApplicationNotResponding [ANR]: false
Qt Version: 6.8.3
Frameworks Version: 6.12.0
Operating System: Linux 6.14.0-33-generic x86_64

-- Information about the crash:
Whenever I unplug my Dell USB-C dock with my external monitors, Kwin-Wayland
will crash. This seems to happen only when Firefox or Zen is open for some
reason, when Chromium or Dolphin or Konsole is opened it does not crash.
The crash can be reproduced every time.
