Do you use "KDE Snap Assistant"?

New crash information added by DrKonqi

kwin_x11 (5.24.6) using Qt 5.15.3

- What I was doing when the application crashed:
Opening the Application Menu and mousing through the list.

- Unusual behavior I noticed:
When you move fast enough down the list, the submenu will not appear and KWin will segfault.

- Custom settings of the application:
Composition is OFF.
List of KWin Scripts loaded:
	- KDE Snap Assist
	- Sticky Window Snapping
No specific window rules applied.
