My project upgrade from cocos2d-x v2.0.4 to 2.1.4,there are two problems:
1.When launch my program,it will display the black frame between the logo display and the first scene switch in a flash,it like a flicker effect.
2.CCControlSwitch will display incorrectly,there are many “Cocos2d: OpenGL error 0x0502” in the console, i test it in the TestCpp demo, the result is the same.
Could anyone give some help?Thanks for that!:)
