      Qt apps show noticeable lag in animation and jitter when scrolling with touchpad when running as native Wayland client while same app runs smooth as XWayland client

      You can see by running template "Qt Quick Application - Scroll" project provided by Qt Creator under both Wayland and XWayland and scrolling with touchpad with mouse pointer in middle of ListView

      Telegram Desktop which uses Qt Widgets also has this problem when scrolling with touchpad Not qt's fault
