Hi,
I am still having this issue after i used the following code thats in the TIPS section.
// prevent flicker
Sprite *sprite = [[Sprite spriteWithFile:@"Default.png"] retain];
sprite.anchorPoint = CGPointZero;
[sprite draw];
[[[Director sharedDirector] openGLView] swapBuffers];
[sprite release];
// Run the intro Scene
[[Director sharedDirector] runWithScene: introScene];
anyone know why its still flickering :(
I am using the same code and it doesn't flicker for me...
cocos 0.8, phone OS 3.0
I tried this solution and while I don't get a black screen flicker any more, I am getting whatever was in the old context.
Ie. if I quit my game, when I relaunch it, it will flicker with a snapshot of the game as it looked when I quit the game last.
Anybody else getting this? I am using cocos2d-0.8.2-rc0.
Thanks
Whenever you quit your app and then do fast relaunch, there is a chance to see snapshot. Especially if you're connected to xCode your app needs more time to quit and disconnect from xCode. Try with a small pause before relaunch and look when there is no more RED light in xCode...
Thanks for the replies!
I'm building against SDK 2.2 on the device. The devices I've used and have experienced this with are iPod Touch 1G, iPhone 3G and iPhone 3GS - all with 3.0.1 OS installed.
I'm going to try what crmagicxxx suggested and let you know the results.
Thanks!
I've figured out what was causing it - OpenFeint!
I was initializing OpenFeint immediately after the -runWithScene call and it was causing this snapshot flicker to occur. I disabled it and all of a sudden, it started working again on all 3 of my devices.
Interesting that it would have this effect, but now I know. Thanks for your help!

I'm a having an issue nearly exactly the same as endloop.
Around 1 time out of 5-10 times it loads up, there is no flicker. But the rest of the time, I get the flicker of whatever the app was displaying last.
I should also mention that I only get this on the release version, not the debug version. I know this because I re-codesign my app store distribution build and add it to my phone and the issue comes up. But it doesn't show when I load a debug version.
One last thing. I init the new scene right before the runwithscene command. If I were to init the new scene before
Sprite *sprite = [[Sprite spriteWithFile:@"Default.png"] retain];
sprite.anchorPoint = CGPointZero;
[sprite draw];
[[[Director sharedDirector] openGLView] swapBuffers];
[sprite release];
then I get just a white screen.
Any help would be greatly appreciated. Thanks.

Put this code in your appDelegate.m file under:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// prevent flicker
Sprite *sprite = [[Sprite spriteWithFile:@"Default.png"] retain];
sprite.transformAnchor = cpvzero;
[sprite draw];
[[[Director sharedDirector] openGLView] swapBuffers];
[sprite release];
// Run the intro Scene
[[Director sharedDirector] runWithScene: introScene];
