    Most likely you are running on a software GL backend. You need to be running on hardware GL backend to have hardware acceleration.

    Firstly,thank you for help.
    I think you are right, and the miniPC I used is pcDuino V2 which support OpenGL ES 2.0 hardware acceleration ,do you know what should be done to let QPaintEngine to recognize that OpenGL ES 2.0 hardware acceleration supported?

    You need Qt built properly for your platform and a proper system configuration. First of all see if other applications/demos (not using Qt) that use OpenGL/ES are hardware accelerated on your system.
