Right-click jumps mouse to center + weird drag behavior after Plasma 6.6 update

Since updating to Plasma 6.6, I’m experiencing a very disruptive input issue that makes basic interaction painful.

  • Whenever I right-click anywhere (desktop, panel, app area), the mouse cursor immediately jumps to the center of the screen.

  • When I try to drag windows by the title bar, the movement behaves strangely — the window jumps or doesn’t follow the cursor properly.
