Comment # 18 on bug 950937 from Alberto Zacchetti

Sorry, you're right, I have only a repo. I was confused (I'm doing a lot of
testing these days...).
Anyway remains the fact that with the downgrade (RC1->Beta1) the problem
remains while upgrading (Beta1->RC1) the problem does not occur. I note, for
clarity, that I do not run the upgrade with the DVD menu option, but with YaST,
selecting the transition of oss repo.
With VLC the bugs are two: one is that of the display, which has already been
opened (https://bugreports.qt.io/browse/QTBUG-48321), while the other is that
once you exit the program (after you start playing a movie), the Plasma5 window
manager crashes: the panel will disappear and also the desktop manager goes out
of service with this dialog window:

KDEInit failed to start �/usr/lib64/libexec/kf5/kioexec�

instead desktop effects continue to run.
