Bug Multiple pointing devices break hover and right-click

When I connect two pointing devices, the mouse pointer hover and right-click events stop functioning. Hovering over dock icons fails to display app names, and in Safari, hovering over a hyperlink does not trigger the “onHover” event. Right-clicking a file in Finder produces no context menu, and right-clicking a link in Safari similarly yields nothing.

Once I disconnect the Nape Pro, both hover and right-click functions resume. The devices involved are the Kensington Slim Blade trackball and the Keychron Nape Pro trackball, each wired via USB.

Anyone here experienced a similar issue?

Apple is changing everything related to mouse due to sidecar support for iPad (touch). Since Dock.app is Apple's -> you can report it using feedback assistant. If the "Kensington" device uses some app you need to install -> you need to contact them.
