我编写了一个简单的QML应用程序，然后部署了它。当我从Qt Creator IDE启动该应用程序时，它运行良好。但是，当我使用windeployqt.exe进行部署时，该应用无法正常运行，当我在Window屏幕之间切换时会有一些轻弹。这是我的代码：
SwitchScreen.pro：
TEMPLATE += app
QT += quick qml
CONFIG += c++11
CONFIG += qtquickcompiler
CONFIG += console
CONFIG+=qml_debug
# The following define makes your compiler emit warnings if you use
# any feature of Qt which as been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS
# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0
SOURCES += \
main.cpp
RESOURCES += qml.qrc
# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =
# Additional import path used to resolve QML modules just for Qt Quick Designer
QML_DESIGNER_IMPORT_PATH =
# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

要部署：在文件夹中包含我的应用程序（SwitchScreen.exe）：windployqt --qmldir <path to project folder> SwitchScreen.exe
然后运行该应用程序，并通过按按钮在屏幕之间切换，屏幕切换不流畅，有些滑动。我不知道为什么，请帮忙！
我正在使用Qt Creator 4.7和Qt 5.11 msvc2017 64位。
更新：如海德建议的那样。我使用procexp检查正在运行的程序。这是输出：
