In System Settings → Task Switcher and check Virtual desktops → check "All other desktops" 2. Press ALT-TAB to switch between tasks 3. OBSERVED RESULT Nothing happens EXPECTED RESULT the running apps should appear and it should be possible to switch between them SOFTWARE/OS VERSIONS KDE Plasma Version: 5.92.0 KDE Frameworks Version: 5.248.0 Qt Version: 6.7.0 Kernel Version: 6.7.0-arch3-1 (64-bit) Graphics Platform: offscreen Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz Memory: 3.7 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 ADDITIONAL INFORMATION I'm seeing this on Plasma6/Qt6 but it has been confirmed on Plasma 5 as well.
I think this works as intended. If you enable this then Alt+Tab switches between all the windows not on the current desktop. If you don't hve any other desktops or there are no windows there then nothing will happen

If you don't hve any > other desktops or there are no windows there then nothing will happen Ah, in that case I misunderstood the intended functionality. I expected that this switch made it possible to switch between all windows regardless on which desktop they occur. That the switch was a choice between: "switch between windows on current desktop only", and "switch between all windows on whatever desktop they may be".
For that you need to uncheck the "Virtual desktops" checkbox
