STEPS TO REPRODUCE 1. Connect at least 2 screens (in this case laptop + 2 screens) 2. Set one of the screens as primary, but move the taskbar to another screen 3. Disconnect secondary screen(s) OBSERVED RESULT Taskbar running as normal, but not being displayed on the only connected display. Restarting does not fix the issue, only fix I have found is reconnecting the external display(s) and moving the taskbar to the primary screen again. EXPECTED RESULT Taskbar being visible on the only connected display (laptop screen) SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.26.3 KDE Frameworks Version: 5.99.0 Qt Version: 5.15.7 Kernel Version: 6.0.7-arch1-1 (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 Manufacturer: Dell Inc.
