Description public+kde 2013-01-02 20:33:08 UTC

Version: 4:4.8.5-0ubuntu0.2

If one hovers over the track of a scrollbar and scrolls using the arrow keys or the scroll wheel *without* moving the mouse pointer in a way that the slider stops under the mouse pointer,
the slider is not properly drawn — it's still in unhovered state. If the mouse pointer is moved, the hover state of the slider is updated and it's drawn correctly.

I don't really know the code, but I suppose an easy fix would be to check the mouse pointer position not only if the mouse pointer is moved but every time the scroll bar sliders' position changes.

Reproducible: Always

Steps to Reproduce:
1. Take a scroll bar
2. Hover over the track
3. Move the slider without moving the mouse pointer
Actual Results:  
Scrollbar slider is not drawn as it should (not hovered/with it's "glow")

Expected Results:  
Scrollbar slider should be in hovered state

Confirmed. I'll look for a fix (your solution looks doable but I'll check in more detail)
