Can you  attach ~/.config/kdeglobals  there is a setting for the drag distance which might be inadvertently set.

I switched to Arch but the problem remains.

I set `StartDragDist` to `200` just to see what happens. It seems that the setting is respected only the first time after KWin restarts and after that, a single pixel movement is enough to start dragging a window, which causes the reported issue. This affects both X11 and Wayland.
