New description:

 For GRIM engine, this error occurs with OpenGL and OpenGLES in fullscreen
 mode (tested on x64 and Raspberry PI2 and 3).

 After some debugging, I came to the conclusion that
 **OpenGLSdlGraphics3dManager::createOrUpdateScreen()** is called before
 the **initSize** method.
 So, variables **_engineRequestedWidth** and **_engineRequestedHeight** are
 still 0; which leads to the creation of a 0x0 frame buffer.
 And causes the error and a black screen at startup.

 A simple test like this at the beginning of **createOrUpdateScreen()**
 works but it is perhaps not the good solution:

 {{{
 if ((_engineRequestedWidth == 0) || (_engineRequestedHeight == 0))
   return;
 }}}
