Bug 508809

Application: kwin_wayland (6.4.4)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.17.0
Operating System: Linux 6.15.10-200.fc42.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)"
DrKonqi: 6.4.4 [CoredumpBackend]

-- Information about the crash:
Hi, today I booted my laptop after a couple of weeks and, after updating everything from both Fedora RPMs and Flathub, I started to experience KWin crashes always under the same circumstance: when I unplug my laptop (Lenovo X1C Gen 10) from its dock (Lenovo USB-C desktop dock) and Firefox (or similar like Floorp) is open. The same issue does *not* happen if another browser is open.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_wayland), signal: Segmentation fault
