QScroller choppy animation on Android

[Andre92]

Hi,
I have a listwidget

QScroller::grabGesture(ui->listWidget, QScroller::LeftMouseButtonGesture);

QScroller::grabGesture(ui->listWidget, QScroller::LeftMouseButtonGesture);

To copy to clipboard, switch view to plain text mode 

On desktop scrolling is smooth no matter how many items i have in the list but on android the animation is choppy both on real device and on emulator.
I'm using

setHorizontalScrollMode(QAbstractItemView::ScrollPerPixel);

setHorizontalScrollMode(QAbstractItemView::ScrollPerPixel);

To copy to clipboard, switch view to plain text mode 

It seems that the gui struggles to render the animation and is very annoying.The feeling is like playing a modern game on a old computer.
Thanks!
