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)
