Bug#864222: kwin-x11: Missing window decorations (crash?) when playing video with ffplay

[Michael Franzl <office@michaelfranzl.com>]

Package: kwin-x11
Version: 4:5.8.6-1
Severity: important

Dear Maintainer,

during normal use of the KDE desktop, when playing any video with `ffplay`
(installed via official Debian repo), window decorations of all windows
disappear with no way of recovery. This happens every time.

Regards,
Michael Franzl
