DropShadowEffect 阻止 QWebEngineView 的显示

Question

我正在尝试在

QWebEngineView

元素中显示 URL 的内容，该元素位于

QFrame

中并应用了

DropShadowEffect

。

但是，这种效果显然导致

QWebEngineView

元素无法刷新内容并保持冻结状态。因为在界面焦点之外执行某些操作之前，

QWebEngineView

元素更新其内容

如果我通过删除

DropShadowEffect

评论这一行，

QWebEngineView

显示没有任何问题

self.shadow_effect([self.ui.frame_render])

        frame_layout = QVBoxLayout()
        self.ui.frame_render.setLayout(frame_layout)

        frame_layout.addWidget(self.show_render())
        

        self.shadow_effect([self.ui.frame_render])

    
        
    def show_render(self):

        graphics_render = QtWebEngineWidgets.QWebEngineView(parent=self.ui.frame_render)
        # Some URL
        graphics_render.setUrl(QUrl("https://www.youtube.com/"))

    def retranslateUi(self, MainWindow):

        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))

如何在 QFrame 上应用

QDropShadowEffect

而不影响

QWebEngineView

的行为？
