New crash information added by DrKonqi

konsole (22.08.3) using Qt 5.15.8

Unlike the first reporter, I don't use a custom background image.

I had my laptop setup to only show the screen on the external monitor. The lid was closed. Then I disconnected the external monitor, which switched the screen to the (suspended) internal one and caused the screen to lock (the laptop itself didn't suspend, it just locks the screen). I then opened the lid, turning the internal monitor on. After unlocking the screen, I could see the Konsole window disappearing as it crashed.

This is happening to me in dolphin possibly because of the embedded konsole. Also on Arch Linux with dual monitors, 23.04.0
