Qt FullScreen problem

laza — Sat, 25 Feb 2017 12:13:18 GMT

Using Qt version 5.2.1, Ubuntu 14.04 (3.14.52) on Nitrogen MAX

C++

int main(int argc, char **argv)
{
QGuiApplication app(argc, argv);
QGst::init(&argc, &argv);
QQmlApplicationEngine view;
QGst::Quick::VideoSurface *surface = new QGst::Quick::VideoSurface;
view.rootContext()->setContextProperty(QLatin1String("videoSurface1"), surface);
view.load(QUrl(QLatin1String("qrc:///main.qml")));
return app.exec();
}

QML:

import QtQuick 2.2
import QtQuick.Controls 1.1
import QtQuick.Layouts 1.1
import QtQuick.Window 2.0
ApplicationWindow {
id: appwin1
visible: true
flags: Qt.FramelessWindowHint
width: 1280
height: 800
...

If I set maximum width and height of display screen or if I use visibility: "FullScreen"

there are several visible problems which do not appear it the size is any smaller than full-screen:

problem with mouse movement - it's like areas where mouse pointer moves do not get repainted correctly
check-boxes wont accept change
drop down boxes wont close upon opening

I know that it is not performance issue as I have tested the same resolution on more displays and the same size works fine if it is not equal to full screen.

Did anyone else had this problem?
