`gre.rendermgr.error`

This event will be generated when an error has occurred with a OpenGL ES 2.0 runtime using the "error_event" option.

Format:

4s1 code 1s0 msg

code :The code is the error code that is returned from the GL framework on the API call glGetError()

msg :The msg is a human readable diagnostic message about the context of the error and any associated resources involved. For example: problems loading font or image resource textures will identify the image and font related to the error, other API calls will be identified by context of execution (ie GL function name, shader compilation).
