I confirm I got this bug. Kubuntu 16.04 originally worked fine after I upgraded. Then various parts of the system stopped working with mouse scroll.
Kate was first. I was able to fix this by reversing the mouse scroll, in settings, then turning mouse scrolling back with the check box. Kate now scrolls. After I did that, the scroll in the Kubuntu Application launcher stopped working. I tried the systems change to no effect. I have rebooted.
