SFML 2.3 depth testing issue

[zerrer]

Hello,
I have noticed that there is an issue with depth testing in sfml 2.3:

Here is a scene rendered using SFML 2.3 lib:

with SFML 2.2 :

And the problem is?

Have you tried to explicitly request a depth-buffer in the context settings when you create the window? As far as I remember, the context selection algorithm has changed, and may lead to contexts without depth-buffer by default.

Well you can see in the first picture that the faces are not sorted correctly. ( some faces far are rendered after faces near )

Here is my opengl configuration ( same for 2 pictures ):

   glEnable(GL_CULL_FACE);
   glEnable(GL_DEPTH_TEST);

   glCullFace(GL_BACK);
   glFrontFace(GL_CCW);

   glEnable(GL_BLEND);
   glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
 

and before rendering:

   glClearColor(63.0f / 255.0f, 203 / 255.0f, 213.0f / 255.0f, 1.0f);
   glClearDepth(1.0f);
   glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

That was it problem solved after specifying depth bits etc.. in context settings. I was using default context settings.

thanks
