Delay in Touch Response When Using QML Up/Down Arrows to Change Value

When using the up and down arrow controls in QML to adjust a value, there is a noticeable delay between the touch input and the value update. This lag affects the responsiveness of the UI and may hinder usability, especially on touch-based interfaces.

Steps to Reproduce:

1. Run the provided QML sample (attached example) on a Raspberry Pi 5 using the Boot2Qt image.

1. Tap the up or down arrow to increase or decrease the value.

1. Observe the delay between the touch event and the actual value change.

Expected Behavior:
The value should update immediately upon touch input on the arrow controls.

Actual Behavior:
There is a visible delay between the touch event and the value change.
