QGLWidget as viewport of QGraphicsView on Android display random pixels randomly

Question

I wrote a game using Qt GraphcisView Framework for Android.

Currently, I use:

• Qt 5.7.1

• Android SDK 28(Android 9.0)

• Android NDK r14b

to build the final apk.

By using QGLWidget, I can see better performance(higher FPS) than using QOpenGLWidget, but sometimes get strange layer of random color pixels over my game scene.

I don't know how this happens, and I've tried many newer version of Qt and Android SDK/NDK, problem remains.

How to solve this?

I'm not sure, but looks like you platform doesn't support OpenGL graphics, take a look on OpenGL ES.
