QOpenGLWidget only show party of QImage in Android

First I use the QWidget to display QImage in android. it works well. But the performance is  bad. So I use QOpenGLWidget to replace the QWidget. The QOpenGLWidget works well in windows and linux platform. But in android the QOpenGLWidget only display part of the QImage.

I use the custom QWidget class to display QImage. When I change the base class from QWidget to QOpenGLWidget, the QImage only display party of the image in android.
