|
|
* you can see that eglCreateImageKHR just refs the native buffer, and eglDestroyImageKHR
|
|
* just unrefs it. Somehow the ref count gets messed up and things are already destroyed
|
|
* by the time eglDestroyImageKHR gets called. For now, at least, just not calling
|
|
* eglDestroyImageKHR should be fine since we do free the GraphicBuffer below.
