Mouse wheel scrolling is slower than in internet browsers

cygnusx-1 Registered Member Posts 17 Karma 0 OS	Mouse wheel scrolling is slower than in internet browsers Sun Dec 20, 2015 12:55 pm Hello Can anyone explain to me why is mouse wheel scrolling in Dolphin slower than in internet browsers? This is very annoying. How can I correct this problem?

luebking Karma 0	Re: Mouse wheel scrolling is slower than in internet browser Wed Dec 23, 2015 9:42 am run "kcmshell5 mouse" and on the second tab adjust the "wheel scrolls by" setting. Scrolling QtQuick views can be slow, but that should not affect the main view in dolphin.
