-[EAGLContext renderbufferStorage:fromDrawable:] Failing the second time on?
Another possible reason is that the size of your layer is too large. In addition make sure you are using a new framebuffer and renderbuffer each time. And you have destroyed your old ones before creating new ones.
You can delete them like this
if let displayFramebuffer = self.displayFramebuffer {
var temporaryFramebuffer = displayFramebuffer
glDeleteFramebuffers(1, &temporaryFramebuffer)
self.displayFramebuffer = nil
}
if let displayRenderbuffer = self.displayRenderbuffer {
var temporaryRenderbuffer = displayRenderbuffer
glDeleteRenderbuffers(1, &temporaryRenderbuffer)
self.displayRenderbuffer = nil
}
