Bug 474440

Application: konsole (23.08.0)

Qt Version: 5.15.10
Frameworks Version: 5.109.0
Operating System: Linux 6.4.12-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
I have a three sccreen setup, where one screen is a ThinkVision M14t touch screen. Normally I don't use the touch but when I do so it crashes the windows where the mouse pointer is in. Even the desktop for that screen crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
