I have this error in all version of Qt ... 5.1 to 5.5 and occur in QML Full Screen mode only

@EmulationQt Ok. Which OS ?
Following code works on my system Qt 5.5 Ubuntu 14.04 64 bit. No blinking.

import QtQuick 2.5
import QtQuick.Window 2.2
import QtQuick.Controls 1.4

Window {
    width: 500
    height: 400

    visibility: "FullScreen"

    ComboBox {
        width: 200
        model: [ "Banana", "Apple", "Coconut" ]
    }
}

May be you should try upgrading OpenGL drivers.

This problem is for Windows only ! Under Windows 7,8 and 10 not Unix families.
Driver already installed.

@EmulationQt Could be related to this QTBUG-45619.

@EmulationQt Well then you should update that bug report or add a new bug with these details and a small example.
