Unable to allocate render buffer storage!

[LhiKien]

If expand MapView to screen frame size, I got "Unable to allocate render buffer storage! 0x15d89650" in console.

If Change:
[self expandMapView:sender animated:YES];
To:
[self expandMapView:sender animated:NO];
The warning disappeared, but animation is canceled.

How to solve this issue?
Thanks for your consideration.
