I have tried that and thought it was working. However, although the gaudy
graphics effects did not reappear, the system froze on three occasions during
the day that I experimented with it. I've returned to 13.2 due to other
problems with Plasma5, namely https://bugs.kde.org/show_bug.cgi?id=341930 and
https://bugs.kde.org/show_bug.cgi?id=354800.  

I'll give it another go to see if the freezes occur again.
