the opengl-es problem with qt


I have some question when enabling opengl-es with Qt on beagleboard; I have compiled the opengl-es and Qt correctly; The test command of the opengl-es also run correctly;

And the content of the file /etc/power.ini is like this:


I have write one class GLWidget which inherit from QGLWidget; Also do some draw action in the paintGL();

If I show the glwidget like this:

GLWidget glwidget;


there is no display error;

But when I show like this:

GLWidget glwidget;

glwidget ->show();

It show some vertical lines on the screen;

It means that if it show with fullscreen,there is no problem. Or, it have the display problem mentioned above(show some vertical lines on the screen)
