Since yesterday my laptop/tablet (a shiftbook/shift13mi) with nixos and kde plasma shows hover click behavior (i.e., whenever I hover my cursor over something clickable like a button or a link a timer is going down and then it clicks the thing). I did not consciously activate it and it is VERY annoying. After a reboot it was still there but I saw the following window attached to this post.
Searching for it so far has only brought me the insight that KDE Plasma should not even have hover click, only gnome has that. Any idea what is going on and how to fix it?
