Frameworks Version: 6.18.0

-- Information about the crash:
KWin_Wayland always crashes when I disconnect my Thunderbolt docking station with external screens. This only happens when programs such as Firefox, Thunderbird or LibreOffice are running; it does not happen when no programs are running, or when only Dolphin or KeepassXC are running.

The crash can be reproduced every time.

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