    Description

      Currently when a QtQuick window is about to be exposed, there are many queued events like focus chain updates and animations that delay sending the NET_WM_SYNC_REQUEST message to the window manager. However, the NET_WM_SYNC_REQUEST message should be sent as early as possible during window creation to allow the window to appear without unnecessary delay because the window manager uses NET_WM_SYNC_REQUEST to control the visibility of a window.
