When Slider is put in a ListView that has pressDelay set moving the slider handle along a horizontal groove is very difficult.
To reproduce open the attached example.
When pressing and sliding the Slider handle the handle should start tracking the touch point after the pressDelay time has elapsed. This is how it works in Qt6. With Qt5 the first attempt at moving the handle usually fail, but after releasing the touch press the second can work, but it's too intermittent.
