To reproduce, in Hello, World AppDelegate.m set up the following:
In AppController application:didFinishLaunchingWithOptions::
CCGLView *glView = [CCGLView viewWithFrame:[window_ bounds]
pixelFormat:kEAGLColorFormatRGB565
depthFormat:GL_DEPTH_COMPONENT16 // (or any other non-zero format)
preserveBackbuffer:NO
sharegroup:nil
multiSampling:YES
numberOfSamples:4];
In MyNavigationController supportedInterfaceOrientations (under iOS 6):
-(NSUInteger)supportedInterfaceOrientations { return
UIInterfaceOrientationMaskAll; }
When attempting to rotate from portrait to landscape, the result is a blank
screen and a logged error Failed to make complete framebuffer object 0x8CD9
generated from within CCES2Renderer resizeFromLayer:, followed by a large
number of OpenGL error 0x0506 errors generated by drawing calls.
This does not occur under cocos2d 1.x.
