I am running Plasma & KWin with Ubuntu 17.04 (Plasma 5.9.4). I am quite new to Plasma. Sometimes I need to scroll inactive window without focusing on it (have 3 screens), but the wheel event is not sent to inactive window - I have to activate it, scroll, focus back. Which would be the setting to tweak that? I am looking into Settings/ Window Behavior and see nothing in that direction. I have Focus stealing prevention set to Medium. Thanks!
