This crash happens under both X11 and Wayland, when using KDDW with QtWidgets and docking.
Issue might affect other systems, I've only replicated under Linux.
Pre-requirements
Use a system with multiple displays.
Test on a QtWidgets application
To replicate
Start any official QtWidgets example that allows docking.
Grab any dock widget out into its own window (or a dock that is already in its own separate window), and let go docking into any other window.
Move the window you just docked into to a different display.
Outcome
KDDW example crashes with: "pure virtual method called"
"terminate called without an active exception"
Crash occurs at: View.cpp#309
The bug appears to have been introduced in commit: e843e8c48aca80361b5f4df43d6ed2590d321119
