-- Information about the crash:
Connected 2 dasy-chained external displays over USB-C. Then konsole crashed. I
am running qt 6.8.1 and konsole 24.12.1.
Unlike mentioned in https://bugs.kde.org/show_bug.cgi?id=492576 this issue is
not fixed in qt 6.8.1
The reporter is unsure if this crash is reproducible.
