Hello. The KDE Discover applications page scrolls to at least 1,000 lines a second when using the touchpad on a 2015 model Macbook Air. Secondly: After plugging in a standard USB mouse the scrolling is too slow on this application. It only scrolls around half a line a second. The application's strange behavior does not match that of Kubuntu. Thanks, Peter
