Here’s a video of the bug: http://youtu.be/EIvf-Ao6u5I
Because of this bug integration between UIKit and Cocos2d-x is practically impossible. After some switching between UIKit and cocos’ views the application will stop rendering opengl calls.
I found the reason. EAGLView is never released and this causes a leak of resources. To resolve the bug in JPSARDA’s example it is sufficient to add the following line:
[[EAGLView sharedEGLView] release];
at the end of CCEGELView::release method. This will solve JPSARDA’s ( and my application ) issues but it is likely that this solution won’t work in projects that handle EAGLView’s lifecycle in a different way.
P.S: In my opinion EAGLView should not be esposed as a singleton. Instead using EAGLView instances will prevent bugs like this one.
