Vertical Slider Tracking
I am developing an app that includes both vertical and horizontal sliders.
The horizontal sliders are working fine. However, the button in the vertical sliders only moves about 90% of the distance that the pointer moves. Thus, the button does not track the pointer very well. The lack of tracking is not a factor of the slider button needing to catch up with the pointer. If the pointer moves a certain distance, the slider button never catches up. The button will stop about 10% short of where it should be.
The lack of tracking (on a vertical slider only) occurs on a mac, a ubuntu box, and my target machine, which uses a touch screen.
I am using Qt 5.8.
