-- Information about the crash:
I was interacting with a QtCreator window when KWin crashed and automatically
restarted. I didn't notice notice/do anything specific, I used this QtCreator
window earlier today as well. I'm pretty sure it's the same as 515123 which I
reported yesterday (where KWin crashed when starting a game).
The reporter is unsure if this crash is reproducible.
