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?
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.
