Logitech K400 PLUS. Touchpad now needs triple tap to double click. I assume the double tap gesture is consumed, but ignored, and the final tap makes for a double tap. Indicating that tap, tap, tap goes to tap, poopypoo, tap -> double_tap OK. This is confirmed by sudo keyd.rvaiya monitor not printing out the poopypoo event.
I'm not sure where in the virtualization this is processed.
