   After migrating to iOS4, I started to get the following error:

   OpenGL error 0x0506 in -[EAGLView swapBuffers], and screen touches were not working.

   After adding CHECK_GL_ERROR in several places, the line

   glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); in CCDirector causes the problem. Apparently the frambuffer is not initialized properly. This happens both in the phone and simulator.

   OpenGL error 0x0506 in -[CCDirector mainLoop]

   Any ideas?

   Thank you!

   Riq,

   I just checked out the latest develop branch version with your new modifications ('EAGLViewTest works on iPad'). Running EAGLViewTest on both the simulator and device with 4.0 gives the following console output:

   I don't know if it's related, by on the latest "Develop" branch code SpriteTest fails with:

   'EAGLView' may not respond to '-setContentScaleFactor'

   I can report it on the issue tracker, if needed.

   thanks

   @boca_jrs: If you see only 1 "OpenGL error in swapBuffers" then it is OK...

   @cjl: fixed, thanks.
