Qt OpenGL is too slow

Hi, NXP and everyone

For IMX6ULL, I'm using fsl-imx-wayland(4.1.15-2.0.1).

I tested Qt example "Cube", in mainwidget.cpp, MainWidget::paintGL() function running of  consume 350ms, and MainWidget::timerEvent() interval was set with 12ms but actually is 4500ms (when MainWidget::paintGL() is empty, it is 11~14ms). So, the scene is drawn with 4.5s interval, too slow. 

 

Please help me to solve this problem.

Best Regards,

Thanks, aither
