OpenGL Flip buffer sometimes fail - SunHpp - Jul 23, 2008 01:33 AM
Hey there I have a little glitch in my iphone game, when I flip screen buffer in opengl, sometimes the screen goes messy, draws goes to one buffer and I can see another backbuffer blinking over it. I dont know if you see what I mean, I can see the exact same problem in the SDK from apple sample called Crash Landing sometimes.
Any idea appreciated !

If you can reproduce the problem in one of apple's sample apps I would report it as a bug

I post into Developers forum on apple.com
I also have another issue using accelerometer :
Hope someone could help us as its a bit annoying before releasing our apps on the store!

Seems to be a bug linked to kEAGLColorFormatRGB565..
Work-around found I use kEAGLColorFormatRGBA8 instead of kEAGLColorFormatRGB565 and it always works :
[eaglLayer setDrawableProperties:[NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:NO], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8/*kEAGLColorFormatRGB565*/, kEAGLDrawablePropertyColorFormat, nil]];
_format = kEAGLColorFormatRGBA8; //kEAGLColorFormatRGB565;

That isn't filing a bug. Those forums are not monitored by Apple at all. Otherwise, people wouldn't be talking about the iPhone SDK there.
If you don't file a bug, it won't get fixed.
