With activated "Filter windows by: Virtual desktops: All other desktops" in KCM, if there are no windows on other Virtual Desktops, pressing Alt+Tab activates "Show Desktop" on current Virtual Desktop. This happens also with deactivated 'Include "Show Desktop" Icon' option. If at all, it should switch to the next Virtual Desktop and show this one, but not the current one. Reproducible: Always Steps to Reproduce: 1. Activate the option 2. Have multiple Virtual Desktops 3. Don't have any windows on other Virtual Desktops 4. Open window on current Vritual Desktop 5. Press Alt+Tab -> Moves window to the side, i.e. shows current Virtual Desktop.
Can reproduce this also on Wayland Operating System: KDE neon Developer Edition KDE Plasma Version: 5.14.80 Qt Version: 5.11.1 KDE Frameworks Version: 5.51.0 Kernel Version: 4.15.0-34-generic OS Type: 64-bit Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz Memory: 7,7 GiB of RAM
Bug persists. Operating System: Arch Linux KDE Plasma Version: 5.15.3 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.2
I observe the same behavior if "Filter windows by" > "Virtual desktops" > "Current desktop" option is enabled and there are no windows on current desktop.
Can confirm the behavior in KDE 5.22.5.
Git commit b31baaf0cd33b0e4469e67a804d2686b13f41b7a by Nate Graham, on behalf of Daniel Lipovetsky. Committed on 04/07/2023 at 13:38. Pushed by ngraham into branch 'master'. tabbox: Show window switcher only when there are two or more windows Previously, we showed the window switcher even if there was only one window, or no windows. Now, we show the window switcher only if there are two or more windows. Note that "desktop" counts as a window when the switcher's "show desktop mode" is enabled.
