Bug 472476

Application: plasmashell (5.27.6)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 6.4.4-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.27.6 [CoredumpBackend]

-- Information about the crash:
Whenever you hover over one application on KDE, it shows a preview of the application window, so when you move your mouse over different programs to select one of them, the behaviour (as I understand) is that the preview is shown and then closed very shortly and it's probably freeing some objects right before some code tries to access it.

This problem happens more often when you move your cursor very quickly over the application icons, but I've seen it happening when moving the cursor very slowly as well. I'm saying in the past because this problem was very apparent in the early months of KWin Wayland implementation, and now it's back again haunting us.

The reporter is unsure if this crash is reproducible.
