KDE Task switcher developed an issue

[local10 <local10@tutanota.com>]

Hi,

Starting about 2-3 weeks ago the KDE task switcher developed an weird issue on my system. The way it used to work, when Alt+Tab was pressed the task switcher would present a list of active windows[1] and then using the upper and lower arrows I could select the window I wanted from the list. Now when when Alt+Tab was pressed the task switcher does not show any list at all, it just switches to the previously used window.

I reinstalled KDE and then reinstalled all installed packages thinking something may have corrupted overtime but the issue is still there. See the following pic for the task manager settings: https://i.postimg.cc/QxJKKNtV/Screenshot-20200807-105314-kde-task-switcher.png

Any ideas? Thanks
