    Unhappy Flickering problem in OpenGL ES game

    I'm developing an OpenGL ES game that is built upon the Crash Landing sample code. There's a flickering / flashing problem that appears from time to time, it causes the display to alternate between the current image (which animates) and a second fixed image (seems to be previous frame buffer value). The flickering appears more often when the rendering fps is increased, in my game using an fps of 30 is enough to reproduce it quite often. The same problem is actually reproducable in Crash Landing, but the fps has to be set to a very high value (at fps of 200, it took me abt 20 tries for it to appear).

    My rendering timer is setup as follows in the applicationDidFinishLaunching method:

    _timer = [NSTimer scheduledTimerWithTimeInterval: (1.0 / kRenderingFPS) target:self selector:@selector(renderScene) userInfo:nil repeats:YES];

    Has anyone encountered a similar problem when developing their games?

    Default

    No code no truth.

    I saw some code lines posted on network with same problem. It mix core animation with OpenGL ES which is suggested to avoid by Apple's document.
