SUMMARY On KDE6, Task Switcher doesn't trigger with alt+tab when there is only one window open STEPS TO REPRODUCE 1. Make sure only one window is open 2. Press alt+tab OBSERVED RESULT Nothing happens EXPECTED RESULT Task switcher triggers and moves focus to window SOFTWARE/OS VERSIONS Linux: 6.5.0-15-generic (64 bit) KDE Plasma Version: 6.0.80 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.1 ADDITIONAL INFORMATION I personally find this disruptive because I frequently use alt-tab to reopen a minimized application or focus onto an open window. In this case there usually is only one application open, and this would not be possible with the current behaviour.

Revert "tabbox: Show window switcher only when there are two or more windows" This reverts commit b31baaf0cd33b0e4469e67a804d2686b13f41b7a. It's still a good idea to show the task switcher even if there's only one window in order to provide the user feedback about their action. Since the task switcher is not shown when there's only one window, it can be confusing and lead to thinking that the task switcher is broken. It also fixes a regression which prevents alt-tabbing to the only remaining minimized window.
