    Description

      Scrolling a Qt Quick Controls 1 ScrollView is very slow on Xorg systems with the xf86-input-libinput driver, while the xf86-input-evded driver is not affected (and neither is Wayland).

      Steps to reproduce:

      • Make sure Xorg is using xf86-input-libinput
      • qmlscene scroll-qqc1.qml
      • Scroll the ListView with the mouse wheel.

      Note that this seems fixed in Qt Quick Controls 2 (tested with the attached scrol-qqc2.qml), but it would be nice to have this fixed in QQC1 as well (as that's heavily used in KDE's Plasma desktop).
