Qt Version: 5.15.3
Frameworks Version: 5.92.0

DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I was watching youtube, and not interacting with the computer directly when KWin crashed.
I hadn't touched it or done anything in that moment. 
There was a youtube video playing. It didn't hiccup, and the desktop seemed to recover pretty rapidly, but I wanted to report the bug.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
