Application: plasmashell (6.1.2) Qt Version: 6.7.2 Frameworks Version: 6.3.0 Operating System: Linux 6.9.8-200.fc40.x86_64 x86_64 Windowing System: Wayland Distribution: "Fedora Linux 40 (KDE Plasma)" DrKonqi: 6.1.2 [CoredumpBackend] -- Information about the crash: I don't know the exact conditions that makes this happen. But it happened more than once after the following sequence: * lock screen * switch away kbd+mouse (KVM) * switch away monitor (monitor input from this box to another, no KVM) * switch away USB sound (dual-USB headphone base) * do stuff on other box * switch back kbd+mouse * switch back monitor * unlock * see Drkonqi + restarted plasma shell If the order of started windows didn't shuffle each time plasma shell restarted, I honestly woulnd't even noticed that (except for Konqi) or cared as much.
