Comment 1 Alexander Mentyu 2018-03-09 12:25:47 UTC
Can't reproduce in:

Plasma: 5.12.2
Apps: 17.12.2
Frameworks: 5.43.0
Qt: 5.10.1
Kernel: 4.14.22-1-MANJARO
OS: Netrunner Rolling

Maybe there are some peculiarities installed or some options?
Comment 2 Justin Zobel 2020-11-20 06:41:46 UTC
Confirmed on 5.20.3 Plasma with KF 5.75.0 and Qt 5.15.1.

Dragged Discover from Favorites to desktop and the mouse cursor disappeared, next moment my session is killed and I'm back at SDDM.
