      since  "xcb: convert last screen to fake when no screen" d8f37d94e537aaab4fa960b80aacabe79bcc14c4 https://codereview.qt-project.org/c/qt/qtbase/+/371170 committed，QGuiApplication::primaryScreen() always return last screen.

      see https://github.com/qt/qtbase/blob/d8f37d94e537aaab4fa960b80aacabe79bcc14c4/src/plugins/platforms/xcb/qxcbconnection_screens.cpp#L537-L540

      xcbScreenNumber always equal to primaryScreenNumber(), so every primaryScreen will setPrimary(true)
