Sorry, I don't understand. What does "value changed twice" mean?

What I mean is that this only prevents the rest of the codepath to run after the value has at least changed once. What if someone sets this value again before everything is properly initialized?

not so sure about that, it would introduce inconsistent special behaviour just in this KCM, as a slider always should react to wheel events.

Yea, I'll remove it. I really don't like this though since you can change by accident the value, when you have the mouse cursor by chance in vertical alignment above or below the slider and then you begin scrolling with the mouse wheel and the slider moves under the cursor.

Happened to me quite often, when I was testing different parts of the ui.
